something like: def bin(x): from math import log bits = (8 if x == 0 else 8*(int(log(x)/log(2))/8+1)) return ''.join([str((x >> i) & 1) for i in range(bits)[::-1]]) though that's probably slow :/ -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/ -- http://mail.python.org/mailman/listinfo/python-list
