starting with # symbol is known as a comment. Python does not execute comments. Comments
are not a part of the program, but they do enhance the interactivity of the program and
make it readable. Python supports two types of comments: Single line comment and Multiline
comment.
Single Line Comment
In case, a user wants to specify a single line comment, then comment must start with the symbol #.
Example:
Program: Output:
#printing a string Hello World
print("Hello world")
Multiple-line Comment
Python does not have a syntax for multiline comments. To add a multiple line comment, you
could insert a # for each line.
Example:
Program : Output :
#printing a string Hello World
#print five names Rachna
print("Hello World")
Sambhav
print("Rachna")
Akshat
print("Sambhav")
Tushar
print("Akshat")
print("Tushar")
However, the text written inside triple quotes (''' or ''"") is also considered as comment. You can
use the triple quotes to write multiline comments. For example:
'''This is """This is
Multiline OR Multiline
Comment''' Comment"""
OPERATORS
In Python, operators can be defined as special symbols which perform arithmetic and logical
computation. The values which the operators use to get the output are called operands.
For example, in the expression 10 – 5, 10 and 5 are operands and the minus (–) sign is the operator.
