如何遍历除列表最后一项之外的所有内容? [英] How to loop through all but the last item of a list?

问题描述

我想遍历一个列表，根据它后面的项目检查每个项目.

I would like to loop through a list checking each item against the one following it.

有什么方法可以循环使用 for x in y 除了最后一个项目之外的所有项目?如果可以，我更愿意不使用索引.

Is there a way I can loop through all but the last item using for x in y? I would prefer to do it without using indexes if I can.

注意

freespace 回答了我的实际问题，这就是为什么我接受了答案，但 SilentGhost 回答了我应该问的问题.

freespace answered my actual question, which is why I accepted the answer, but SilentGhost answered the question I should have asked.

对于造成的混乱深表歉意.

Apologies for the confusion.

推荐答案

for x in y[:-1]

如果 y 是一个生成器，那么上面的将不起作用.

If y is a generator, then the above will not work.
