5 Best Ways to Find the Number of 1 bits in a Given Number in Python

💡 Problem Formulation: When working with binary numbers in Python, a common task is to count the number of 1 bits, also known as set bits, in the binary representation of a number. For example, given the input number 13, which is 1101 in binary, the desired output would be 3 as there are three 1 bits in its binary representation.

Get the the number of zeros and ones of a binary number in Python

In Python, the shortest and most efficient way is to just turn it into a binary string and count the '1's: def ones(num): # Note that bin is a built-in return bin(num).count('1') You can get the number of zeros by subtracting ones(num) from the total number of digits.

Python: How to efficiently count the number of "1"s in the binary representation of 1 to n numbers?

It might be more efficient to remove the n == 1 check, since most inputs will have to unsuccessfully check that, slowing down most inputs (and most recursive calls). Also, bitwise stuff like if n & 1 == 0 and m = n >> 1 (in front of the if to handle both cases) will likely speed things up a tiny bit. ...
