Random Separate Element into 2 Lists

Idea from my friend, who wonder about how to generating 2 random list from a list of person. Original blog could be found here.

code.py

import random

group_1 = ['some', 'one', 'like', 'you']

group_2 = [group_1.pop(random.randint(0, len(group_1)-1))      # element from group_1 also removed by pop().
           for i in group_1]                                   # size of group_1 is decreasing each loop,
                                                               # this make group_2 stop adding new element
                                                               # when it's size larger or equal to group_1.
