Zip with list output instead of tuple

Question

What is the fastest and most elegant way of doing list of lists from two lists?

I have

In [1]: a=[1,2,3,4,5,6]

In [2]: b=[7,8,9,10,11,12]

In [3]: z         


        

Answer 1

List comprehension would be very simple solution I guess.

a=[1,2,3,4,5,6]

b=[7,8,9,10,11,12]

x = [[i, j] for i, j in zip(a,b)]

print(x)

output : [[1, 7], [2, 8], [3, 9], [4, 10], [5, 11], [6, 12]]
