List comprehension would be faster, lookup would be even faster but would have to generate list or dictionary ahead of time but this will work on any length int up 2 limit of int does not pad with zeros on most significant end to word length. n=input() l=[] while(n>0): l.append(str(n&1)); n=n>>1 I posted this here http://www.uselesspython.com/download.php?script_id=222 a while back. -- http://mail.python.org/mailman/listinfo/python-list
