How to reduce two 2 dimensional array to column sums

[NobbZ]

You need to make the tuples lists again after that.

Google’s first hit for transposing a list in Elixir was a thread in this forum:

Transpose a list of lists using list comprehension

Coming from Python and its version of list comprehensions, I am looking for a way to accomplish in Elixir, transposition of a list of lists. Here is single line Python version: >>> m = [[1,2],[3,4],[5,6]] >>> rez = [[m[j][i] for j in range(len(m))] for i in range(len(m[0]))] >>> rez [[1, 3, 5], [2, 4, 6]] I would like to keep it short and elegant, if possible! Thanks for your help!
