Python Input and Output

Python has  input() and print() function used for standard input and output operations respectively.

Output  with  print() function

The  print() function is used to  output the data to the screen(standard output device or console).

Example  using print() function

print('Print display message on screen')

Another example of using print:

x = 5

print( 'The value of x  is ', x)

Output

Example  Using sep and end arguments of print() function

The syntax of the print() function is:

print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False)

The argument, objects is the value(s) to be printed.

The  argument sep separator is used between the values. The  default value of sep is a space character.

 end value is printed after all the values are printed  The default value of end is  new line.

The file is the object where the value(s ) is printed and its default value is sys.stdout (console or screen).

print('Print ','multiline', 'output to screen', sep='\n')

#Output

#Print

#multiline

#output to screen

​​​​​​​print('Python', 'is', 'easy to', 'learn', sep=' ')

#Output Python is easy to learn

print('Python', 'is', 'easy to', 'learn', sep=',', end='#')

#Output  Python,is,easy to,learn#

Output

Print 

multiline

output to screen

Output Python is easy to learn

​​​​​​​Output  Python,is,easy to,learn#

Python Input

To accept the  input from the user python has input() function to allow this. The syntax for  function  input()  is:

input([prompt])

The  prompt is the string you want to display on the screen. It is an optional argument.

name = input('Enter your name:')

Vijay

print(name)

Example  reading an integer using input

#convert the string to integer using int() function

​​​​​​​num = int(input('Enter a number:'))

Enter a number: 10

print(num)

#Output 10

Example  reading a float value using input

#convert the string to integer using int() function

amount = int(input('Enter amount:'))

Enter amount: 1000.78

print(amount)

#Output 1000.78
