What is Python?

Python is a high-level programming language which is

  • Interpreted :- Python is process at runtime by the interpreter.
  • Interactive :- You can use a python prompt & interact with the interpreter directly to write your program.

Python Indentation

  • Indentation means the space from margin to the begin of characters in a line.
  • Most of the programming languages are use brace { } to define block of code. Python uses indentation.
  • A code of block (body,loop,etc) starts with indentation and ends with the first unindented line. The block of indentation is up to you.
  • Generally, whitespace is used for indentation.
  • For eg,
if True:
   print "True"
else:
   print "False"

Python comments

A comments is text that doesn’t affect on code, it just text to let someone to understand your code what you have done in program. It helpful when you want to change in your program or solve errors. And when you read comment then you can understand the purpose of code. Comments are useful to understand your code when you are no longer to use it.

Types of Comments in Python

  1. Single line comment
  2. Multiple line comment

Single line comment

Python single line comment start with # (hashtag) special character with no white spaces and last till the end of line.

Print(“welcome to Foss TechNix”)

Multiple line comment

Example:

‘’’
This is 
Multiline
Comment
‘’’
Print(“welcome”)
