python input and output function in hindi by unitdiploma

Input Function

•To accept input from keyboard, Python provides the input() function. This function takes a value from the keyboard and returns it as a string.

Example:

  str=input(‘enter you city: ‘)

  print(str)

  str=input(‘enter a number: ‘)

  x=int(str)

  print(x)

  x=int(input(‘enter any no.: ‘))

  print(x)

  x=float(input(‘enter any no.: ‘))

  print(x)

Output:
enter you city: gorakhpur
gorakhpur
enter a number: 4
4
enter any no.: 54
54
enter any no.: 37.5
37.5
 

Output Function

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

  print(‘This sentence is output to the screen’)

          # Output: This sentence is output to the screen

  a = 5

  print(‘The value of a is’, a)

    # Output: The value of a is 5

Examples of Output Function

print(‘hello’)

print(‘hello \tPython’)

print(‘hello ‘*3)

print(‘hello’+’Python’)

a,b=2,4

print(a)

print(a,b)

print(a,b,sep=”,”)

print(a,b,sep=”:”)

print(a,b,sep=”____”)

print(“hello”)

print(“welcome”,end=””)

print(“python”)

print(1,2,3,sep=”,”,end=”&”)

Examples of Output Function

a,b,c=24,25,27

print(‘num1={}’.format(a))

a,b,c=10,20,30

print(‘num1={},num2={},num3={}’.format(a,b,c))

print(‘num1={0},num2={1},num3={2}’.format(a,b,c))

print(‘num1={2},num2={1},num3={0}’.format(a,b,c))

name,sal=’amit’,35200.00

print(‘Hi {0}, your salary is {1}’.format(name,sal))

print(‘Hi {x}, your salary is {s}’.format(x=name,s=sal))

Program to sum of two numbers

  b = int(input(“enter second number: “)) 

  sum= a + b

   print(“Sum of two numbers is:”, sum)
