Puzzles!
def maxindex(seq):
return max(zip(seq, itertools.count()))[1]
maxindex([1, 1, 0]) => 1, but I think it should be 0 ;)

Hmm... well, going for complex rather than terse...
def minindex(seq, index=0):
if len(seq) == index+1:
return index
rest = minindex(seq, index+1)
return rest if seq[rest] < seq[index] else index
Whee! I haven't see the Python ternary expression "out in the wild yet". Fun!
Happy Hacking!
