Data Types

                A data type specifies the type of value a variable can contains. For example, a person’s name
                must be stored as a string value whereas the person’s age must be stored as an integer. 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                          Hello World
                       #print five names                            Rachna
                       print("Hello World")                         Sambhav
                       print("Rachna")                              Akshat
                       print("Sambhav")                             Tushar
                       print("Akshat")

                       print("Tushar")


                                                                  Introduction to Python Programming  115
