Data types in Python are:
int: Positive or negative whole numbers (without any fractions). Example: a = 3
float: Any real number in which a fraction is denoted by a decimal symbol. Example: a = 3.5
string: A string value is a collection of one or more characters put in single or double quotes. Example:
a="hello"
COMMENTS IN PYTHON
Comments in Python can be used to explain parts of the code. It can also be used to hide the code as
well. Comments enable us to understand the way a program works. In python, any statement 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 Rakesh
#print five names Rachna
print("Rakesh") 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"""
