How to take integer input in Python?

In Python, the built-in input() function always returns a string. To take integer input, the string must be typecast into an integer using the int() function. This article demonstrates multiple ways to take integer input in Python with examples.

Example 1: Taking Single Integer Input

Output

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

Explanation:

• input() returns a string by default.
• int(a) converts the input to an integer.

Example 2: Taking Multiple Inputs Separately

Output

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

Explanation:

• The first input remains a string.
• The second input is converted to an integer using int()

Example 3: Taking Multiple Integer Inputs in a List

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]

Explanation:

• split() separates the input string into a list of strings.
• List comprehension with int(x) converts each element to an integer.

Example 4: Taking Integer Input with List Size

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]
