WebMar 10, 2013 · How do you like this one: def bitsoncount (x): b = 0 bit = 1 while bit <= x: b += int (x & bit > 0) bit = bit << 1 return b. Basically, you use a test bit that starts right and gets shifted all the way through up to the bit length of your in parameter. For each position the bit & x yields a single bit which is on, or none.
