<p> <span style="background-color: white; color: #5799b9; font-family: poppins; font-size: 20px; text-align: center;">Microsoft Azure</span></p><p><span style="background-color: white; color: #5799b9; font-family: poppins; font-size: 20px; text-align: center;">1:3. Microsoft Azure - Windows</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">There are many cloud computing platforms offered by different organizations. Windows Azure is one of them, which is provided by Microsoft. Azure can be described as the managed data centers that are used to build, deploy, manage the applications and provide services through a global network. The services provided by Microsoft Azure are PaaS and IaaS. Many programming languages and frameworks are supported by it.</span></p><p><span style="background-color: white; color: #01a1df; font-family: poppins; font-size: 17px;">Azure as PaaS (Platform as a Service)</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">As the name suggests, a platform is provided to clients to develop and deploy software. The clients can focus on the application development rather than having to worry about hardware and infrastructure. It also takes care of most of the operating systems, servers and networking issues.</span></p><p><span style="background-color: white; color: #01a1df; font-family: poppins; font-size: 18px;">Pros</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ The overall cost is low as the resources are allocated on demand and servers are automatically updated.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ It is less vulnerable as servers are automatically updated and being checked for all known security issues. The whole process is not visible to developer and thus does not pose a risk of data breach.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ Since new versions of development tools are tested by the Azure team, it becomes easy for developers to move on to new tools. This also helps the developers to meet the customers demand by quickly adapting to new versions.</span></p><p><span style="background-color: white; color: #01a1df; font-family: poppins; font-size: 18px;">Cons</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ There are portability issues with using PaaS. There can be a different environment at Azure, thus the application might have to be adapted accordingly.</span></p><p><span style="background-color: white; color: #01a1df; font-family: poppins; font-size: 17px;">Azure as IaaS (Infrastructure as a Service)</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ It is a managed compute service that gives complete control of the operating systems and the application platform stack to the application developers. It lets the user to access, manage and monitor the data centers by themselves.</span></p><p><span style="background-color: white; color: #01a1df; font-family: poppins; font-size: 18px;">Pros</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ This is ideal for the application where complete control is required. The virtual machine can be completely adapted to the requirements of the organization or business.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ IaaS facilitates very efficient design time portability. This means application can be migrated to Windows Azure without rework. All the application dependencies such as database can also be migrated to Azure.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ IaaS allows quick transition of services to clouds, which helps the vendors to offer services to their clients easily. This also helps the vendors to expand their business by selling the existing software or services in new markets.</span></p><p><span style="background-color: white; color: #01a1df; font-family: poppins; font-size: 18px;">Cons</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ Since users are given complete control they are tempted to stick to a particular version for the dependencies of applications. It might become difficult for them to migrate the application to future versions.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ There are many factors which increases the cost of its operation. For example, higher server maintenance for patching and upgrading software.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ There are lots of security risks from unpatched servers. Some companies have welldefined processes for testing and updating on-premise servers for security vulnerabilities. These processes need to be extended to the cloud-hosted IaaS VMs to mitigate hacking risks.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ The unpatched servers pose a great security risk. Unlike PaaS, there is no provision of automatic server patching in IaaS. An unpatched server with sensitive information can be very vulnerable affecting the entire business of an organization.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ It is difficult to maintain legacy apps in Iaas. It can be stuck with the older version of the operating systems and application stacks. Thus, resulting in applications that are difficult to maintain and add new functionality over the period of time.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ It becomes necessary to understand the pros and cons of both services in order to choose the right one according your requirements. In conclusion it can be said that, PaaS has definite economic advantages for operations over IaaS for commodity applications. In PaaS, the cost of operations breaks the business model. Whereas, IaaS gives complete control of the OS and application platform stack</span></p><p><span style="background-color: white; color: #01a1df; font-family: poppins; font-size: 17px;">Azure Management Portal</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">Azure Management Portal is an interface to manage the services and infrastructure launched in 2012. All the services and applications are displayed in it and it lets the user manage them.</span></p><p><span style="background-color: white; color: #01a1df; font-family: poppins; font-size: 18px;">Getting started</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">◆ A free trial account can be created on Azure management portal by visiting the following link - manage.windowsazure.com</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">The screen that pops up is as shown in the following image. The account can be created using our existing Gmail, Hotmail or Yahoo account.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">Once logged in, you will be redirected to the following screen, where there is a list of services and applications on the left panel.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">When you click on a category, its details are displayed on the screen. You can see the number of applications, virtual machine, mobile services and so on by clicking on the menu item.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">The next chapter contains a detailed explanation of how to use this portal to manage Azure services.</span></p>

Cloud Computing - Overview</span></b></span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">The popular trend in today's technology driven world is Cloud Computing. Cloud computing can be referred to as the storing and accessing of data over the internet rather than your computer's hard drive. This means you don't access the data from either your computer's hard drive or over a dedicated computer network (home or office network). Cloud computing means data is stored at a remote place and is synchronized with other web information.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">One prominent example of cloud computing is Office 365 which allows users to store, access, edit their MS Office documents online (in browser) without installing the actual program on their device.</span></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEj3J8fIIUB0rKE_nKhFJQFdtLaNBI855-u9vxrhKI4spW0WtVr5LbruGHU7b35pm5Qo1mWJ_1K1PtUSoortEtYFVyju_IzF-xcx0ZXStMcKUoNA7oFjRpFcB3vi8XMpsXJa9Qp82_Bsb0hlzZQ8hfXuSKGI-z3Yp_ECdFSBMGZYNGv50Tnu51zpRvM1=s902" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="649" data-original-width="902" height="230" src="https://blogger.googleusercontent.com/img/a/AVvXsEj3J8fIIUB0rKE_nKhFJQFdtLaNBI855-u9vxrhKI4spW0WtVr5LbruGHU7b35pm5Qo1mWJ_1K1PtUSoortEtYFVyju_IzF-xcx0ZXStMcKUoNA7oFjRpFcB3vi8XMpsXJa9Qp82_Bsb0hlzZQ8hfXuSKGI-z3Yp_ECdFSBMGZYNGv50Tnu51zpRvM1=s320" width="320" /></a></div><br /><p><b style="color: #01a1df; font-family: poppins;"><span style="font-size: large;">Architecture of Cloud Computing</span></b></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">The architecture of cloud computing comprises of the following components −</span></p><p><span style="background-color: white; font-family: poppins;">★ Front-end device</span></p><p><span style="background-color: white; font-family: poppins;">★ Back-end platform</span></p><p><span style="background-color: white; font-family: poppins;">★ Cloud-based delivery</span></p><p><span style="background-color: white; font-family: poppins;">★ Network</span></p><p><b style="background-color: white; font-family: poppins; font-size: 16px;">Front-end Devices</b><span style="background-color: white; font-family: poppins; font-size: 16px;"> </span><span style="background-color: white; font-family: poppins; font-size: 16px;">− These are basically the devices that are used by clients to access the data or program using the browser or special applications.</span></p><p><b style="background-color: white; font-family: poppins; font-size: 16px;">Back-end Platform</b><span style="background-color: white; font-family: poppins; font-size: 16px;"> </span><span style="background-color: white; font-family: poppins; font-size: 16px;">− There are various computers, servers, virtual machines, etc. that combine to become a back-end platform.</span></p><p><span style="background-color: white; color: #01a1df; font-family: poppins; font-size: 17px;">Types of Cloud</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">The storage options on cloud is in 3 forms −</span></p><p><span style="background-color: white; font-family: poppins;">★ Public</span></p><p><span style="background-color: white; font-family: poppins;">★ Private</span></p><p><span style="background-color: white; font-family: poppins;">★ Hybrid</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEiwX2en4cMMo2-5fqstIJXTIIvR-Huz_icVQ2QTNRtVKlnNx8M4e5bT9rucg5sbu9tVyLx-Z8vJLt-3e7gXigN6xMmmztdn0KNaLG9vK-WKpYyXjmSHd5xHhcfI2nCfZLpL_6UpXKQob9YpQ0-rCm3DqJ1TScOUysPycme5pBBKLzGLO9UxeBBIQoRR=s906" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="669" data-original-width="906" height="236" src="https://blogger.googleusercontent.com/img/a/AVvXsEiwX2en4cMMo2-5fqstIJXTIIvR-Huz_icVQ2QTNRtVKlnNx8M4e5bT9rucg5sbu9tVyLx-Z8vJLt-3e7gXigN6xMmmztdn0KNaLG9vK-WKpYyXjmSHd5xHhcfI2nCfZLpL_6UpXKQob9YpQ0-rCm3DqJ1TScOUysPycme5pBBKLzGLO9UxeBBIQoRR=s320" width="320" /></a></div><br /><span style="background-color: white; font-family: poppins;"><br /></span><p></p><p><b style="background-color: white; font-family: poppins; font-size: 16px;">Public Cloud</b><span style="background-color: white; font-family: poppins; font-size: 16px;"> − A service provider makes the clouds available to the general public which is termed as a public cloud. These clouds are accessed through internet by users. These are open to public and their infrastructure is owned and operated by service providers as in case of Google and Microsoft.</span></p><p><b style="background-color: white; font-family: poppins; font-size: 16px;">Private Cloud</b><span style="background-color: white; font-family: poppins; font-size: 16px;"> − These clouds are dedicated to a particular organization. That particular organization can use the cloud for storing the company's data, hosting business application, etc. The data stored on private cloud can't be shared with other organizations. The cloud is managed either by the organization itself or by the third party.</span></p><p><b style="background-color: white; font-family: poppins; font-size: 16px;">Hybrid Cloud</b><span style="background-color: white; font-family: poppins; font-size: 16px;"> − When two or more clouds are bound together to offer the advantage of both public and private clouds, they are termed as Hybrid Cloud. Organizations can use private clouds for sensitive application, while public clouds for non-sensitive applications. The hybrid clouds provide flexible, scalable and cost-effective solutions to the organizations.</span></p><p><span style="background-color: white; color: #01a1df; font-family: poppins; font-size: 17px;">Benefits of Cloud</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">There are many benefits of clouds. Some of them are listed below.</span></p><p><span style="background-color: white; font-family: poppins; font-size: 16px;">★ Cloud service offers scalability.

<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
Programming tutorials since the beginning of time have started with a little program called "Hello, World! The syntax changed in Python 3.0. If you are using Python 3.0, you should be reading <a href="https://en.wikibooks.org/wiki/Non-Programmer%27s_Tutorial_for_Python_3" style="background-image: none; color: #0b0080;" title="Non-Programmer's Tutorial for Python 3">Non-Programmer's Tutorial for Python 3</a> instead. So here is the Python 2.6 example:</div>
<div class="mw-geshi mw-code mw-content-ltr" dir="ltr" style="background-color: #f9f9f9; border: 1px dashed rgb(47, 111, 171); direction: ltr; font-family: monospace, Courier; font-size: 13px; line-height: 1.1em; orphans: 2; padding: 1em; widows: 2;">
<div class="python source-python" style="font-family: monospace; line-height: normal;">
<pre class="de1" style="background-image: none; border: 0px none white; font-size: 1em; line-height: 1.2em; padding: 0px; vertical-align: top;"><span class="kw1" style="color: #ff7700; font-weight: bold;">print</span> <span class="st0" style="color: darkslateblue;">"Hello, World!"</span>
</pre>
</div>
</div>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
If you are using the command line to run programs then type it in with a text editor, save it as <code style="background-color: #f9f9f9; font-family: monospace, Courier;">hello.py</code> and run it with <code style="background-color: #f9f9f9; font-family: monospace, Courier;">python hello.py</code></div>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
Otherwise go into IDLE, create a new window, and create the program as in section <a href="https://en.wikibooks.org/wiki/Non-Programmer%27s_Tutorial_for_Python_2.6/Intro#Creating_and_Running_Programs" style="background-image: none; color: #0b0080;" title="Non-Programmer's Tutorial for Python 2.6/Intro">Creating and Running Programs</a>.</div>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
When this program is run here's what it prints:</div>
<pre style="background-color: #f9f9f9; border: 1px dashed rgb(47, 111, 171); font-family: monospace, Courier; font-size: 13px; line-height: 1.3em; orphans: 2; padding: 1em; widows: 2;">Hello, World!</pre>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
Now I'm not going to tell you this every time, but when I show you a program I recommend that you type it in and run it. I learn better when I type it in and you probably do too.</div>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
Now here is a more complicated program:</div>
<div class="mw-geshi mw-code mw-content-ltr" dir="ltr" style="background-color: #f9f9f9; border: 1px dashed rgb(47, 111, 171); direction: ltr; font-family: monospace, Courier; font-size: 13px; line-height: 1.1em; orphans: 2; padding: 1em; widows: 2;">
<div class="python source-python" style="font-family: monospace; line-height: normal;">
<pre class="de1" style="background-image: none; border: 0px none white; font-size: 1em; line-height: 1.2em; padding: 0px; vertical-align: top;"><span class="kw1" style="color: #ff7700; font-weight: bold;">print</span> <span class="st0" style="color: darkslateblue;">"Jack and Jill went up a hill"</span>
<span class="kw1" style="color: #ff7700; font-weight: bold;">print</span> <span class="st0" style="color: darkslateblue;">"to fetch a pail of water;"</span>
<span class="kw1" style="color: #ff7700; font-weight: bold;">print</span> <span class="st0" style="color: darkslateblue;">"Jack fell down, and broke his crown,"</span>
<span class="kw1" style="color: #ff7700; font-weight: bold;">print</span> <span class="st0" style="color: darkslateblue;">"and Jill came tumbling after."</span>
</pre>
</div>
</div>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
When you run this program it prints out:</div>
<pre style="background-color: #f9f9f9; border: 1px dashed rgb(47, 111, 171); font-family: monospace, Courier; font-size: 13px; line-height: 1.3em; orphans: 2; padding: 1em; widows: 2;">Jack and Jill went up a hill
to fetch a pail of water;
Jack fell down, and broke his crown,
and Jill came tumbling after.</pre>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
When the computer runs this program it first sees the line:</div>
<div class="mw-geshi mw-code mw-content-ltr" dir="ltr" style="background-color: #f9f9f9; border: 1px dashed rgb(47, 111, 171); direction: ltr; font-family: monospace, Courier; font-size: 13px; line-height: 1.1em; orphans: 2; padding: 1em; widows: 2;">
<div class="python source-python" style="font-family: monospace; line-height: normal;">
<pre class="de1" style="background-image: none; border: 0px none white; font-size: 1em; line-height: 1.2em; padding: 0px; vertical-align: top;"><span class="kw1" style="color: #ff7700; font-weight: bold;">print</span> <span class="st0" style="color: darkslateblue;">"Jack and Jill went up a hill"</span>
</pre>
</div>
</div>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
so the computer prints:</div>
<pre style="background-color: #f9f9f9; border: 1px dashed rgb(47, 111, 171); font-family: monospace, Courier; font-size: 13px; line-height: 1.3em; orphans: 2; padding: 1em; widows: 2;">Jack and Jill went up a hill</pre>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
Then the computer goes down to the next line and sees:</div>
<div class="mw-geshi mw-code mw-content-ltr" dir="ltr" style="background-color: #f9f9f9; border: 1px dashed rgb(47, 111, 171); direction: ltr; font-family: monospace, Courier; font-size: 13px; line-height: 1.1em; orphans: 2; padding: 1em; widows: 2;">
<div class="python source-python" style="font-family: monospace; line-height: normal;">
<pre class="de1" style="background-image: none; border: 0px none white; font-size: 1em; line-height: 1.2em; padding: 0px; vertical-align: top;"><span class="kw1" style="color: #ff7700; font-weight: bold;">print</span> <span class="st0" style="color: darkslateblue;">"to fetch a pail of water;"</span>
</pre>
</div>
</div>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
So the computer prints to the screen:</div>
<pre style="background-color: #f9f9f9; border: 1px dashed rgb(47, 111, 171); font-family: monospace, Courier; font-size: 13px; line-height: 1.3em; orphans: 2; padding: 1em; widows: 2;">to fetch a pail of water;</pre>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
The computer keeps looking at each line, follows the command and then goes on to the next line. The computer keeps running commands until it reaches the end of the program.</div>
<h4 style="background-color: white; background-image: none; border-bottom-style: none; font-size: 15px; line-height: 19.1875px; margin: 0px 0px 0.3em; orphans: 2; overflow: hidden; padding-bottom: 0.17em; padding-top: 0.5em; widows: 2;">
<span class="editsection" style="float: right; font-size: 13px; font-weight: normal; margin-left: 5px;"></span><span class="mw-headline" id="Terminology">Terminology</span></h4>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
Now is probably a good time to give you a bit of an explanation of what is happening - and a little bit of programming terminology.</div>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
What we were doing above was using a <i>command</i> called <code style="background-color: #f9f9f9; font-family: monospace, Courier;">print</code>. The <code style="background-color: #f9f9f9; font-family: monospace, Courier;">print</code> command is followed by one or more <i>arguments</i>. So in this example</div>
<div class="mw-geshi mw-code mw-content-ltr" dir="ltr" style="background-color: #f9f9f9; border: 1px dashed rgb(47, 111, 171); direction: ltr; font-family: monospace, Courier; font-size: 13px; line-height: 1.1em; orphans: 2; padding: 1em; widows: 2;">
<div class="python source-python" style="font-family: monospace; line-height: normal;">
<pre class="de1" style="background-image: none; border: 0px none white; font-size: 1em; line-height: 1.2em; padding: 0px; vertical-align: top;"><span class="kw1" style="color: #ff7700; font-weight: bold;">print</span> <span class="st0" style="color: darkslateblue;">"Hello, World!"</span>
</pre>
</div>
</div>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
there is one <i>argument</i>, which is <code style="background-color: #f9f9f9; font-family: monospace, Courier;">"Hello, World!"</code>. Note that this argument is a group of characters enclosed in double quotes ("). This is commonly referred to as a <i>string of characters</i>, or <i>string</i>, for short. Another example of a string is <code style="background-color: #f9f9f9; font-family: monospace, Courier;">"Jack and Jill went up a hill"</code>.</div>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
A command and its arguments are collectively referred to as a <i>statement</i>, so</div>
<div class="mw-geshi mw-code mw-content-ltr" dir="ltr" style="background-color: #f9f9f9; border: 1px dashed rgb(47, 111, 171); direction: ltr; font-family: monospace, Courier; font-size: 13px; line-height: 1.1em; orphans: 2; padding: 1em; widows: 2;">
<div class="python source-python" style="font-family: monospace; line-height: normal;">
<pre class="de1" style="background-image: none; border: 0px none white; font-size: 1em; line-height: 1.2em; padding: 0px; vertical-align: top;"><span class="kw1" style="color: #ff7700; font-weight: bold;">print</span> <span class="st0" style="color: darkslateblue;">"Hello, World!"</span>
</pre>
</div>
</div>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
is an example of a statement.</div>
<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
That's probably more than enough terminology for now.</div>
<h3 style="background-color: white; background-image: none; border-bottom-style: none; font-size: 17px; line-height: 19.1875px; margin: 0px 0px 0.3em; orphans: 2; overflow: hidden; padding-bottom: 0.17em; padding-top: 0.5em; widows: 2;">

<div style="background-color: white; font-size: 13px; line-height: 19.1875px; margin-bottom: 0.5em; margin-top: 0.4em; orphans: 2; widows: 2;">
Here is another program:</div>
<div class="mw-geshi mw-code mw-content-ltr" dir="ltr" style="background-color: #f9f9f9; border: 1px dashed rgb(47, 111, 171); direction: ltr; font-family: monospace, Courier; font-size: 13px; line-height: 1.1em; orphans: 2; padding: 1em; widows: 2;">
<div class="python source-python" style="font-family: monospace; line-height: normal;">

In this example, the print command is followed by two arguments, with each of the arguments separated by a comma. So with the first line of the program</div>

The first argument is the string <code style="background-color: #f9f9f9; font-family: monospace, Courier;">"2 + 2 is"</code> and the second argument is the <i>mathematical expression</i> <code style="background-color: #f9f9f9; font-family: monospace, Courier;">2 + 2</code>, which is commonly referred to as an <i>expression</i>.</div>

What is important to note is that a string is printed as is (the string is what is within the double quotes but doesn't include the double quotes themselves. So the string is printed without the enclosing double quotes.) But an <i>expression</i> is <i>evaluated</i>, (in other words, converted) to its actual value.</div>

Often in programming you are doing something complicated and may not in the future remember what you did. When this happens, the program should probably be commented. A<i>comment</i> is a note to you and other programmers explaining what is happening. For example:</div>
<div class="mw-geshi mw-code mw-content-ltr" dir="ltr" style="background-color: #f9f9f9; border: 1px dashed rgb(47, 111, 171); direction: ltr; font-family: monospace, Courier; font-size: 13px; line-height: 1.1em; orphans: 2; padding: 1em; widows: 2;">

Notice that the comment starts with a hash: <code style="background-color: #f9f9f9; font-family: monospace, Courier;">#</code>. Comments are used to communicate with others who read the program and your future self to make clear what is complicated.</div>
