# Check if Binary representation is Palindrome in Python

• Last Updated : 11 May, 2022

Given an integer ‘n’, write a Python function that returns true if binary representation of x is palindrome else return false. Examples:

```Input : n = 9
Output : True
Binary representation of n=9 is 1001 which
is palindrome as well.

Input : n = 10
Output : False
Binary representation of n=10 is 1010 which
is not palindrome.```

We have existing solution for this problem please refer Check if binary representation of a number is palindrome link. We can solve this problem in python very quickly. Approach is very simple,

1. Convert given number into it’s binary representation using bin(num) function.
2. Now reverse binary representation string of number and compare it with original binary represented string, if both are equal that means binary representation of number is palindrome else not.
3.

Note : We can use other approach of checking a string is palindrome or not

## Python

 `# Function to check if binary representation of``# a number is palindrome or not` `def` `binarypalindrome(num):` `     ``# convert number into binary``     ``binary ``=` `bin``(num)` `     ``# skip first two characters of string``     ``# because bin function appends '0b' as``     ``# prefix in binary representation of``     ``# a number``     ``binary ``=` `binary[``2``:]` `     ``# now reverse binary string and compare``     ``# it with original``     ``return` `binary ``=``=` `binary[``-``1``::``-``1``]` `# Driver program``if` `__name__ ``=``=` `"__main__":``    ``num ``=` `9``    ``print` `binarypalindrome(num)`

Output:

`True`
