def to_base(number, base):
'converts base 10 integer to another base'
number = int(number)
base = int(base)
if base < 2 or base > 36:
raise ValueError, "Base must be between 2 and 36"
if not number:
return 0
symbols = string.digits + string.lowercase[:26]
answer = []
while number:
number, remainder = divmod(number, base)
answer.append(symbols[remainder])
return ''.join(reversed(answer))
Hope this helps,
Michael
