如何从元组列表中提取第n个元素? [英] How to extract the n-th elements from a list of tuples?

问题描述

我正在尝试从元组列表中获取第n个元素.

I'm trying to obtain the n-th elements from a list of tuples.

我有类似的东西:

elements = [(1,1,1),(2,3,7),(3,5,10)]

我希望仅将每个元组的第二个元素提取到列表中:

I wish to extract only the second elements of each tuple into a list:

seconds = [1, 3, 5]

我知道可以通过for循环来完成，但是我想知道是否还有另一种方法，因为我有成千上万的元组.

I know that it could be done with a for loop but I wanted to know if there's another way since I have thousands of tuples.

推荐答案

n = 1 # N. . .
[x[n] for x in elements]
