Puzzles!
def maxindex(seq):
return max(zip(seq, itertools.count()))[1]
maxindex([1, 1, 0]) => 1, but I think it should be 0 ;)
Man, that makes it a lot harder...
def maxindex(seq):
return -max(zip(seq, (-i for i in itertools.count())))
Seems like count should take a step argument, then I could just use
itertools.count(0, -1), ala:
def count(start=0, step=1):
while 1:
yield start
start += step
