Input and Output functions

Input and output functions

input ( )

It refers to the data whatever we enter or the data entered by a user. Python supports two built-in functions for reading input namely input( ) supported in the latest versions and raw_input( ) supported upto python 2.x versions.

Ex:

>>> input( )                                                                      #inbuilt function

A python programmer

‘A python programmer’

>>> var=input(“Enter a number:”)                             #giving integer as input

Enter a number: 5

>>> var1=int(input(“The number is:”))                     #another way to give integer as input

The number is: 7

>>> x=str (input(“Your string is:”))                            #Giving string as input

Your string is: orange

 

>>> v1=input(“you entered:”)

you entered: 16.13

>>> print(v1)

16.13

print( ) statement

To print anything you need print( ) statement. The usage of print( ) is explained in the below examples:

>>> a=5

>>> print(a)

5

>>> a=”5″

>>> print(a)

5

>>> a=”A Print function”

>>> print(a)

A Print function

>>> print(‘a’)                                       #using single quote

a

>>> print(“a”)                                     #using double quote

a

>>> “hi”

‘hi’

>>> ‘hi’

‘hi’

Python uses some command operators to print. Following are some of the examples.

>>> print (‘V’+’M’+’S’)                             #’plus’ for concatenating two strings into a single string

VMS

>>> print (“V”+”M”+”S”)

VMS

>>> print(“520″+”+”+”6”)

520+6

>>> print(“520″+”+”+”6″+”=”+”526”)

520+6=526

>>> print(“VMS,”+”Welcomes you all”)

VMS,Welcomes you all

 

>>> print(“A”,”Step”,”To”,”Learn”)             # ‘comma’ for printing multiple strings in a line

A Step To Learn

Note: If you want to print multiple lines/a paragraph you can use ’’’ (triple quotes)

>>> print(“hi\nhello”)                                  #here \n is to print on new line or next line

hi

hello

>>> print(“Hi\nI am Sudhakar\nWelcome to all”)

Hi

I am Sudhakar

Welcome to all

 

>>> print(“coding\tis\teasy”)                     # here \t is used to print tab separated line

coding is          easy

>>> print(“coding\tis easy”)

coding    is easy
