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:

Python 
# take input from user
input_a = input()

# print data type
print(type(input_a))

# type cast into integer
input_a = int(input_a)

# print data type
print(type(input_a))

Output:

100
<class 'str'>
<class 'int'>

Example 2:

Python 
# string input
input_a = input()

# print type
print(type(input_a))

# integer input
input_b = int(input())

# print type
print(type(input_b))

Output:

10
<class 'str'>
20
<class 'int'>

Example 3:

Python 
# take multiple inputs in array
input_str_array = input().split()

print("array:", input_str_array)

# take multiple inputs in array
input_int_array = [int(x) for x in input().split()]

print("array:", input_int_array)

Output:

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:

Python 
# Python program to take integer input  in Python

# 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]
