. It returns the input string by striping trailing newline. In Python 3.x raw_input()
method renamed to input()

Basic Syntax
Following is the basic syntax for raw_input() function:
In Python 2.x:
You can use the raw_input() function as:
age = raw_input("Enter your age : ") print 'your age is ', age
In Python 3.x:
You can use the input() function as:
age = input("Enter your age : ") print 'your age is ', age
Return Value
raw_input() function in Python 2.x or input() function in Python 3.x returns the input string taken from user’s input.
Example
Following are the examples for raw_input() and input() functions:
Example 1 : Python 2.x, raw_input() function
import math print "Program for calculating the area of circle and square." length = raw_input("Enter the length of the square: ") area_of_square = length**2 print "Area of the square is: ", area_of_square radius = raw_input("Enter the radius of the circle: ") area_of_circle = (radius**2) * math.pi print "Area of the circle is: ", area_of_circle
The output for the above program is as given below:
Area of the square is: 100
Enter the radius of the circle: 10
Area of the circle is: 314.159265359
Example 2 : Python 3.x, input() function
import math print "Program for calculating the area of circle and square." length = input("Enter the length of the square: ") area_of_square = length**2 print "Area of the square is: ", area_of_square radius = input("Enter the radius of the circle: ") area_of_circle = (radius**2) * math.pi print "Area of the circle is: ", area_of_circle
The output for the above program is as given below:
Area of the square is: 100
Enter the radius of the circle: 10
Area of the circle is: 314.159265359
