在Python中使用索引迭代列表 [英] Iterate a list with indexes in Python

问题描述

我可以发誓我已经看过接受列表的函数(或方法)，例如[3, 7, 19]并将其放入可重复的元组列表中，例如:[(0,3), (1,7), (2,19)]使用它代替:

I could swear I've seen the function (or method) that takes a list, like this [3, 7, 19] and makes it into iterable list of tuples, like so: [(0,3), (1,7), (2,19)] to use it instead of:

for i in range(len(name_of_list)):
    name_of_list[i] = something

但是我不记得这个名字了，谷歌搜索迭代列表"一无所获.

but I can't remember the name and googling "iterate list" gets nothing.

推荐答案

>>> a = [3,4,5,6]
>>> for i, val in enumerate(a):
...     print i, val
...
0 3
1 4
2 5
3 6
>>>
