I've tried to figure out the correct indentation for this, and came up
with<br><br>
========================================<br>
import string<br><br>
def to_base(n, base):<br>
'converts base 10 integer to another base, up thru
base 36'<br>
n = int(n)<br>
base = int(base) <br>
if base < 2 or base > 36:<br>
raise ValueError, "Base
must be between 2 and 36" <br>
if not n:<br>
return 0<br>
symbols = string.digits + string.lowercase[:26] <br>
answer = []<br>
while n:<br>
n, remainder = divmod(n,
base)<br>
answer.append(symbols[remainder]) <br>
return ''.join(reversed(answer))<br>
n = 12<br>
base = 36<br>
print to_base(n, base)<br>
==========================================<br>
This seems to work fine for n >= base, but not for n < base. For
example, the code shown returns "c". Is my indentation wrong,
or the code? It seems to me that the code should work for the general
case, not just for n >= base.<br><br>

<dd>How 'bout you hack a from_base function and email it back to me?
(hint: type 'help(int)' in the python interpreter).<br><br>
