Python Program To Check If a Number is Odd or Even
Let’s now see how to check if a number is odd or even using Python code.
It is as simple as ABC. We will take input from the user and then check if the number is divisible by 2 or not. If the number is divisible by 2, it is an even number; otherwise, the given number is odd.
We will check the divisibility using the modulo operator (%) and use if-else Python statements to print if the number is odd or even.
Here’s the code for the same.
#Python program to check if a number is odd or even
#Input number from user
number = int(input("Enter a number to check odd or even \n"))
#Checking if the nunmber is divisible by 2 or not
#If the number is divisible by 2 then it is an even number
if (number % 2) == 0:
print("Number is even")
#If the number is not divisble by 2 then it is an odd number
else:
print("Number is odd")
Output:
Here’s the output of the above program.

Python Program to Check Whether a Given Number is Even or Odd Recursively
Source Code:
def evenOrOdd(n):
#if remainder is 0 then num is even
if(n % 2 == 0):
return True
#if remainder is 1 then num is odd
elif(n %2 != 0):
return False
else:
return evenOrOdd(n)
# Input by geeks
num = int(input("Enter a number to check if it is odd or even"))
if(evenOrOdd( num )):
print(num ,"The given number is even")
else:
print(num ,"The given number is odd")
Output:
Python Program To Check Even and Odd Numbers In a List
Source Code:
#create a list of numbers
numlist = [23, 34, 45, 56, 57, 68, 89]
#for loop to check if the number is odd or even in the list
for i in numlist:
if i%2 == 0:
print(i,"- Even")
else:
print(i,"- Odd")
Output:

Python Program to Print Even Numbers from 1 to 100 Using While Loop
Source Code:
print("Even numbers between 1 to 100 using while loop")
num = 2
while num <= 100:
print(num)
num += 2
Output:
