# Python Program to Check Even or Odd Using Bitwise Operator

In the previous article, we have discussed Python Program to Set nth Bit of a Number

Given a Number and the task is to check if the given number is even or odd using the bitwise operator.

Bitwise & Operator:

If both bits are 1, sets each bit to 1.

Examples:

Example1:

Input:

Given Number = 251

Output:

The Number given is an Odd Number

Example2:

Input:

Given Number = 54

Output:

The Number given is an Even Number

## Program to Check Even or Odd Using Bitwise Operator in Python:

Below are the ways to check if the given number is even or odd using the bitwise operator in python:

### Method #1: Using Bitwise &(and) Operator (Static Input)

Approach:

• Give the number as static input and store it in a variable.
• Apply bitwise & operation for the given number and 1 and store it in another variable say evn_or_od.
• Pass the above result to the if conditional statement.
• If the statement is true, then print “The Number given is an Odd Number”.
• Else print “The Number given is an Even Number”.
• The Exit of the Program.

Below is the implementation:

# Give the number as static input and store it in a variable.
gvn_numb = 251
# Apply bitwiseÂ & operation for the given number and 1 and store it in another variable
# say evn_or_od.
evn_or_od = gvn_numb & 1
# Pass the above result to the if conditional statement.
if (evn_or_od):
# If the statement is true, then print "The Number given is an Odd Number".
print("The Number given is an Odd Number")
else:
# Else print "The Number given is an Even Number".
print("The Number given is an Even Number")


Output:

The Number given is an Odd Number

### Method #2: Using Bitwise &(and) Operator (User Input)

Approach:

• Give the number as user input using the int(input()) function and store it in a variable.
• Apply bitwise & operation for the given number and 1 and store it in another variable say evn_or_od.
• Pass the above result to the if conditional statement.
• If the statement is true, then print “The Number given is an Odd Number”.
• Else print “The Number given is an Even Number”.
• The Exit of the Program.

Below is the implementation:

# Give the number as user input using the int(input()) function and
# store it in a variable.
gvn_numb = int(input("Enter some random number = "))
# Apply bitwiseÂ & operation for the given number and 1 and store it in another variable
# say evn_or_od.
evn_or_od = gvn_numb & 1
# Pass the above result to the if conditional statement.
if (evn_or_od):
# If the statement is true, then print "The Number given is an Odd Number".
print("The Number given is an Odd Number")
else:
# Else print "The Number given is an Even Number".
print("The Number given is an Even Number")



Output:

Enter some random number = 32
The Number given is an Even Number
