How to take integer input in Python? (original) (raw)

Last Updated : 26 Jul, 2024

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]
