Python Programming

Python is a terrific programming language. It's syntax is simple and code length is short which makes it's easy to understand and write.

Python uses indentation for managing code blocks, instead of curly braces as in other programming languages. Both tabs and spaces are supported, but the standard indentation requires to use four spaces.

Lest's see this example of conditional statement

						
>>>a=5
