How to generate the elements of the Pascal's triangle, in Python?

Comment

"""
This implementation demonstrates how to
generate the elements of Pascal's
triangle (https://en.wikipedia.org/wiki/Pascal%27s_triangle).

Let n be the number of rows to create.

Time complexity: O(n^2)
Space complexity: O(1)
