Python merge single nested lists

Question

I have a variable that holds lists

 s=[16, 29, 16] 
   [16, 16, 16]

I want to combine them like this

 combined = [16,16]
            [29,16]
            [16,16]

The world is irrational. Some (similar) questions get downvoted and some upvoted! — devnull

Use zip function, like this

s = [[16, 29, 16], [16, 16, 16]]
print zip(*s)
# [(16, 16), (29, 16), (16, 16)]

If you want the output to be a list of lists, then you can simply do

print map(list, zip(*s))
# [[16, 16], [29, 16], [16, 16]]

@user2243831 Please be specific when you ask questions. Edit your question to include all the relevant details to the question, sample input and expected output. Otherwise we both would be wasting our time.
