对于任何可迭代项，跳过第一项：
itercars \= iter(cars)
next(itercars)
for car in itercars:
# do work
如果您想跳过最后一步，您可以：
itercars \= iter(cars)
# add 'next(itercars)' here if you also want to skip the first
prev \= next(itercars)
for car in itercars:
# do work on 'prev' not 'car'
# at end of loop:
prev \= car
# now you can do whatever you want to do to the last one on 'prev'
