Python defines operations for the union, intersection, difference, and symmetric difference of sets. Write a Python program where you create several sets and experiment with these operators. Then, using only these operators, write an isSubset method that takes two sets A and B and returns true if A is a subset of B and false otherwise. Note that this operator is not commutative (e. g., A is a subset of B does not mean that B is a subset of A - make sure A is the first parameter in your method)
