I was trying to come up with something in one line which could zip a list of list in one line.

arr=[[1,2,3],[4,5,6],[7,8,9]]
reduce(zip,arr,[])

The output I would want would be similar to : zip([1,2,3],[4,5,6],[7,8,9]) which is [(1, 4, 7), (2, 5, 8), (3, 6, 9)]

Any help would be appreciated.

`zip(*arr)` will give you the output so what are you asking? – Padraic Cunningham Oct 10 '15 at 09:08
zipping list and transposing a matrix are very different . Please explain the similarity. – Akshay Hazari Oct 10 '15 at 09:08
@ Padraic Cunningham Yes . that is what I wanted . You could put that as an answer – Akshay Hazari Oct 10 '15 at 09:10

it is in the dupe, another way to do it in python2 would be `map(None,*arr)` – Padraic Cunningham Oct 10 '15 at 09:29
