Introduction

Python is a popular programming language.
Python can be used on a server to create web applications.

It is used for:
web development (server-side),
software development,
mathematics,
system scripting.

Why Use Python?
Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc).
Python has a simple syntax similar to the English language.
Python has syntax that allows developers to write programs with fewer lines than some other programming languages.
Python runs on an interpreter system, meaning that code can be executed as soon as it is written. This means that prototyping can be very quick.
Python can be treated in a procedural way, an object-oriented way or a functional way.

Python Indentation
Indentation refers to the spaces at the beginning of a code line.
Where in other programming languages the indentation in code is for readability only, the indentation in Python is very important.
Python uses indentation to indicate a block of code.
Python will give you an error if you skip the indentation
The number of spaces is up to you as a programmer, but it has to be at least one.
You have to use the same number of spaces in the same block of code, otherwise Python will give you an error

Comments:-
Comments can be used to explain Python code.
Comments can be used to make the code more readable.
Comments can be used to prevent execution when testing code.
Comments starts with a #, and Python will ignore them
Python does not really have a syntax for multi line comments.
To add a multiline comment you could insert a # for each line
Or, not quite as intended, you can use a multiline string.
Since Python will ignore string literals that are not assigned to a variable, you can add a multiline string (triple quotes) in your code, and place your comment inside it
As long as the string is not assigned to a variable, Python will read the code, but then ignore it, and you have made a multiline comment.
