Nettet23. mar. 2012 · For arbitrary-length integers, bin (n).count ("1") is the fastest I could find in pure Python. I tried adapting Óscar's and Adam's solutions to process the integer in 64-bit and 32-bit chunks, respectively. Both were at least ten times slower than bin (n).count ("1") (the 32-bit version took about half again as much time).
