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
# 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:
Python3
# 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:
Python3
# take multiple inputs in arrayinput_str_array = input().split()print("array:", input_str_array)# take multiple inputs in arrayinput_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:
Python3
# 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 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]
