Boustrophedon def create_zigzag(rows, cols, start = 1): This function creates a list of lists that represents a two-dimensional grid with the given number of rows and cols. This grid should contain the integers counting the rows * cols numbers from start in ascending order. However, similar to the way an on slowly plows a eld somewhere back in ancient Greece, the elements of every oddnumbered row must be listed in descending order. However you choose to enforce that discipline is up to you. In all of the examples of the following table, the keyword parameter start is not given and therefore equals one. But your function must work correctly for arbitrary values of start. Expected result [[1, 2, 3, 4, 5], [13, 9, s, 7, 6], [11, 12, 13, 14, 15]] [[1], [2], [3], [4], [5], [6], in. [8]. [9], [13]] [[1, 2], [4, 3], [5, 6]: [8, 7]]
