循环遍历包含内容和索引的列表 [英] Loop through list with both content and index

问题描述

循环遍历python列表以获取内容和它们的索引是很常见的.我通常做的事情如下:

It is very common for me to loop through a python list to get both the contents and their indexes. What I usually do is the following:

S = [1,30,20,30,2] # My list
for s, i in zip(S, range(len(S))):
    # Do stuff with the content s and the index i

我觉得这个语法有点难看，尤其是 zip 函数内部的部分.有没有更优雅/Pythonic 的方法来做到这一点?

I find this syntax a bit ugly, especially the part inside the zip function. Are there any more elegant/Pythonic ways of doing this?

推荐答案

使用 enumerate 内置函数:http://docs.python.org/library/functions.html#enumerate
