Definition. A Pythagorean triple (x, y, z) is a triple of positive integers where x² + y² = z². This can be thought of as describing an x × y rectangle with the property that the diagonal z is also of integer length. A Pythagorean triple (x, y, z) is primitive if x, y, z are coprime (i.e. there is no integer k > 1 which divides all of them). (a) Write a Python function PrimPyth (n) which returns a list of primitive Pythagorean triples (x, y, z) where 0 < x < y < z
