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-inint() function.
Let us see the examples:
Example 1:
Python# take input from userinput_a=input()# print data typeprint(type(input_a))# type cast into integerinput_a=int(input_a)# print data typeprint(type(input_a))
Output:
100
<class 'str'>
<class 'int'>
Example 2:
Python# string inputinput_a=input()# print typeprint(type(input_a))# integer inputinput_b=int(input())# print typeprint(type(input_b))
Output:
10
<class 'str'>
20
<class 'int'>
Example 3:
Python# take multiple inputs in arrayinput_str_array=input().split()print("array:",input_str_array)# take multiple inputs in arrayinput_int_array=[int(x)forxininput().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 listn=int(input("Enter the size of list : "))# store integers in a list using map, split and strip functionslst=list(map(int,input("Enter the integer elements of list(Space-Separated): ").strip().split()))[:n]print('The list is:',lst)# printing the listOutput:
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]
