In this example, you will learn to check whether a number entered by the user is even or odd.
To understand this example, you should have the knowledge of the following Python programming topics:
A number is even if it is perfectly divisible by 2. When the number is divided by 2, we use the remainder operator % to compute the remainder. If the remainder is not zero, the number is odd.
Source Code
# Python program to check if the input number is odd or even.
# A number is even if division by 2 gives a remainder of 0.
# If the remainder is 1, it is an odd number.
num = int(input("Enter a number: "))
if (num % 2) == 0:
print("{0} is Even".format(num))
else:
print("{0} is Odd".format(num))
Output 1
Enter a number: 43 43 is Odd
Output 2
Enter a number: 18 18 is Even
In this program, we ask the user for the input and check if the number is odd or even. Please note that { } is a replacement field for num.
