Here's a sketch; I'll leave you to fill in the details -- you may wish to guard against interesting input like b < 2. >>> def anybase(n, b, digits='0123456789abcdef'): ... tmp = [] ... while n: ... n, d = divmod(n, b) ... tmp.append(digits[d]) ... return ''.join(reversed(tmp)) ... >>> anybase(1234, 10) '1234' >>> anybase(7, 2) '111' >>> [anybase(64, k) for k in range(2, 17)] ['1000000', '2101', '1000', '224', '144', '121', '100', '71', '64', '59', '54', '4c', '48', '44', '40'] >>> HTH, John -- http://mail.python.org/mailman/listinfo/python-list
