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()orraw_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.
Video Demonstration :
You can also watch the video on YouTube here.
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
Python Program to check even number - Test Case 2: Positive odd number
Python Program to check odd number - Test Case 3: Negative even number
Python Program to check even negative number - Test Case 4: Negative odd number
Python Program to check zero as even or odd - Test Case 5: Zero
Python Program to check even or odd number
