In this post, We will see how to take integer input in Python. As we know that Python’s built-in input() function always returns a str(string) class object. So for taking integer input we have to type cast those inputs into integers by using Python built-in int() function.

Let us see the examples:

Example 1:

Python3 

10 20 30 40 50 60 70
array: ['10', '20', '30', '40', '50', '60', '70']
10 20 30 40 50 60 70
array: [10, 20, 30, 40, 50, 60, 70]

Example 4:

Python3

# input size of the list
n = int ( input ( "Enter the size of list : " ))
# store integers in a list using map, split and strip functions
lst = list ( map ( int , input (
"Enter the integer elements of list(Space-Separated): " ).strip().split()))[:n]
print ( 'The list is:' , lst) # printing the list

Output: 

Enter the size of list : 4
Enter the integer elements of list(Space-Separated): 6 3 9 10
The list is: [6, 3, 9, 10]
