Python Program to find whether an integer is even or odd number

Hello everyone, welcome to Programming In Python. In this post, I will develop a simple logic to check whether an integer is an even or odd number in Python. Any number(positive/negative) which is divisible by the number 2 is declared as an even number and numbers( positive/negative ) which are not divisible by the number 2 are declared as odd numbers.

Even or Odd – Code Visualization

Task :

To check whether an integer is an even number or an odd number.

Approach :

• Read an input integer using input() or raw_input().
• When the input is divided by 2 and leaves a remainder 0, it is said to be EVEN number.
• When the input is divided by 2 and leaves any remainder other than 0, it is said to be ODD number.
• When an input is 0 it is said to be even.
• The same conditions apply to negative integers too.

Program :

input_num = int(input('Enter any number: '))

if input_num % 2 == 0:
    print(input_num, "is EVEN")
else:
    print(input_num, "is ODD")

Output :

• Test Case 1: Positive even number
  

  

• Test Case 2: Positive odd number
  

  

• Test Case 3: Negative even number
  

  

• Test Case 4: Negative odd number
  

  

• Test Case 5: Zero
