<h2>Steps to Install Python:</h2>
<ol style="list-style-type: lower-alpha;">
<li>Visit the official python website: <a href="https://www.python.org/">https://www.python.org/</a></li>
<li>Download the executable file based on your Operating System and version specifications.</li>
<li>Run the executable file and complete the installation process.</li>
</ol>
<h4>Version:</h4>
<p>After installation check the version of python by typing following command: &lsquo;python --version&rsquo;.</p>
<p>&nbsp;</p>
<h2>Starting Python:</h2>
<p>Open Python IDE or any other text editor of your preferred choice. Let&rsquo;s understand python code execution with the simplest print statement. Type the following in the IDE:&nbsp;</p>
<pre class="language-python"><code>print("Hello World !!!")</code></pre>
<p>Now save the file with a .py extension and Run it. You will get the following output:</p>
<pre class="language-markup"><code>Hello World !!!</code></pre>
<p>&nbsp;</p>
<h2>Installing Packages:</h2>
<p>To install packages in Python, we use the <strong>pip </strong>command.&nbsp;<br>e.g. pip install "Package Name"</p>
<p>Following command installs pandas package in Python</p>
<pre class="language-python"><code>pip install pandas</code></pre>
<p><br>We will learn more about the pip command in the chapter dedicated to pip.</p>
