python - Splitting a list of strings with a delimiter and adding to new lists

Question

This is my list:

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

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

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

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

first = []
second = []

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

Answer 1

You can use zip:

names = ['blue v orange', 'white v black', 'red v brown']  
first, second = map(list, zip(*map(lambda x:x.split(' v '), names)))  
print(first)
print(second)

Output:

['blue', 'white', 'red'] 
['orange', 'black', 'brown']
