如何从元组列表中提取第 n 个元素
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)]
我希望只将每个元组的第二个元素提取到一个列表中:
I wish to extract only the second elements of each tuple into a list:
seconds = [1, 3, 5]
我知道这可以通过 for 循环来完成，但我想知道是否还有其他方法，因为我有数千个元组.
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.
解决方案
n = 1 # N. . .
[x[n] for x in elements]
