Combining list of list of string by columns in python

Question

I have a situation here.

What I have is

s = [['A','C','E'],['B','D','F'],...]

I need to merge the string vertically, meaning I need to get the result of

res = [['A','B',..], ['C','D',..],['E','F',..]].

How do I get it ?

Thank you

You could use zip method in combination with unpacking operator.

res = [list(item) for item in zip(*s)]

Output

> res
[['A', 'B'], ['C', 'D'], ['E', 'F']]
