input() function

2.2 Input() Function:

In python, the input from keyboard or user can take using input() function.

print(“Enter your name : “)
x=input()
print(“Hello,”+ x )

Output:
Enter your name :
Harish     #input from keyboard
Hello,Harish

We can use following function also to accept input from keyboard

x=raw_input()

The difference is that raw_input() does not exist in Python 3.x, while input() does. Actually, the old raw_input() has been renamed to input()

 

Forms of input() functions:

1. if we want to skip print function then 

x=input("Enter your name")

OR

x=raw_input("Enter your name")

 

2. if you want to specify type of input then

x=int(input("Enter integer number : "))

can also use.

Example:

def swap(num1,num2):
    temp=num1    
    num1=num2    
    num2=temp
#Accept two numbers
num1=int(input("Enter first Number : ")
num2=int(input("Enter Second Nummber : ")

In above program we have accepted two integer numbers.
