Python for AIHard

A table is stored as a list of rows. You want it the other way round: a list of columns.

Write flip(grid) that returns a new list of lists where row i of the result is column i of the original.

grid = [[1, 2], [3, 4], [5, 6]]

returns [[1, 3, 5], [2, 4, 6]]

grid = [[1, 2, 3], [4, 5, 6]]

returns [[1, 4], [2, 5], [3, 6]]

grid = []

returns []
