Matrix Transpose in Python

Question

I am trying to create a matrix transpose function for python but I can\'t seem to make it work. Say I have

theArray = [[\'a\',\'b\',\'c\'],[\'d\',\'e\',\'f\         


        

Answer 1

This one will preserve rectangular shape, so that subsequent transposes will get the right result:

import itertools
def transpose(list_of_lists):
  return list(itertools.izip_longest(*list_of_lists,fillvalue=' '))
