def dec2bin(x): return x and (dec2bin(x/2)+str(x%2)) or '' does the same job without lambda or Python 2.5 (and note that the usual warning about a and b or c doesn't apply here as b is guaranteed to evaluate as true). -- \S -- [EMAIL PROTECTED] -- http://www.chaos.org.uk/~sion/ "Frankly I have no feelings towards penguins one way or the other" -- Arthur C.
