<h1>Let&#8217;s Start with python Installation</h1>
<p>Download Python for your respective windows from here: <a href="https://www.python.org/downloads/" target="_blank" rel="noopener noreferrer">https://www.python.org/downloads/</a></p>
<h1><strong>The Basics of Python:</strong></h1>
<p><strong>Python</strong> is an interpreted programming language, this means that as a developer you write Python (.py) files in a text editor and then put those files into the python interpreter to be executed.</p>
<p><strong>Python</strong> is very simple and straightforward language. <strong>Python</strong> is an interpreted programming language, this suggests that as a developer you write Python (.py) files during a text editor then put those files into the python interpreter to be executed.</p>
<p>I believe you have installed <strong>python</strong> in your system. If not, please go to the below Installation module as priority so that you can practice alongside.</p>
<p>The Python Script Mode:</p>
<p>Invoking the interpreter with a script parameter begins execution of the script and continues until the script is finished. When the script is finished, the interpreter is not any longer active.</p>
<p>The simplest directive in Python is that the “print” directive — it simply prints out a line.<br/>
Let’s write our first Python file, called helloworld.py,<br/>
which may be wiped out any text editor.<br/>
Python files have extension .py.</p>
<p>Type the following source code in a helloworld.py file:</p>
<blockquote>
<pre>print("Hello, World!")</pre>
</blockquote>
<p>We have assumed that you have Python interpreter set in PATH variable. Now, try to run this program as follows −</p>
<blockquote>
<pre>$ python helloworld.py</pre>
</blockquote>
<p>The Python Command Line:</p>
<p>To test a short amount of code in python sometimes it is quickest and easiest not to write the code in a file. This is made possible because Python are often run as an instruction itself.</p>
<p>Type the following on the Windows, Mac or Linux command line.</p>
<p>Invoking the interpreter without passing a script file as a parameter brings up the following prompt:</p>
<blockquote>
<pre>$ python
Python 3.8.0 (default, Nov 14 2019, 22:29:45) [GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>&gt;&gt;</pre>
</blockquote>
<p>Type the following text at the Python prompt and press the Enter:</p>
<blockquote>
<pre>$ python
Python 3.8.0 (default, Nov 14 2019, 22:29:45) [GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>&gt;&gt; print("Hello, World!")</pre>
</blockquote>
<p>resultant to above statements:</p>
<blockquote>
<pre>$ python
Python 3.8.0 (default, Nov 14 2019, 22:29:45) [GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>&gt;&gt; print("Hello, World!")
Hello, World!</pre>
</blockquote>
<p>Whenever you are done in the python command line, you can simply type the following to quit the python command line interface.</p>
<blockquote>
<pre>&gt;&gt;&gt; exit()</pre>
</blockquote>
