用定界符分割字符串列表并添加到新列表 [英] Splitting a list of strings with a delimiter and adding to new lists

问题描述

这是我的清单:

names = ['blue v orange', 'white v black', 'red v brown']  

我想按' v '拆分它们，并附加到这样的新列表中:

I want to split them by ' v ' and append to a new list like this:

['blue', 'white', 'red']  # first
['orange', 'black', 'brown']  # second

拆分后如何添加它们?以下代码不起作用:

How can I append them after splitting? The below code does not work:

first = []
second = []

for x in names:
    first, second = x.split(' v ')

推荐答案

这是一个pythonic解决方案:

Here is a pythonic solution:

names = ['blue v orange', 'white v black', 'red v brown']

x, y = list(zip(*(k.split(' v ') for k in names)))

x  # ('blue', 'white', 'red')
y  # ('orange', 'black', 'brown')
