Transpose matrix

Transposes a two-dimensional list.

  • Use *lst to get the provided list as tuples.
  • Use zip() in combination with list() to create the transpose of the given two-dimensional list.
def transpose(lst):
  return list(zip(*lst))
transpose([[1, 2, 3], [4, 5, 6], [7, 8, 9], [10, 11, 12]])
# [(1, 4, 7, 10), (2, 5, 8, 11), (3, 6, 9, 12)]
