if I have 2 lists

list1 = ['a', 'b', 'c', 'd']

list2= ['e', 'f', 'g', 'h', 'i', 'k']

and output I want is:

list3 = [['a' , 'e'] , ['b' , 'f'], ['c', 'g h'], ['d', 'i k']]

example is kind of short in length,

I want to know how to pair 'c' with 'g h' and 'd' with 'i k' in a list of list using python 3
