Introduction to Python for Discrete Math 1) Using Python to implement Set operations 2) Using Python to implement functions Python programming: Please define functions to implement the following set operations using Python: (1) set_union(A, B) (2) set_intersection (A,B) (3) set_difference (A,B) (4) |set_isSubSet (A,B) (to test if set A is a subset of set B ) (5) isProperSubset (to test if set A is a proper subset of set B ) Here are some reference code def set union (A,B) : return A.union (B) Please use the following code as tester: defTest01():A={1,2,8}B={1,2,3,4,5}print(set,union(A,B))print(setintersection(A,B))print(setdifference(A,B))print(setdifference(B,A))print(set,issubset(A,B))print(setBispropersubset(A,B))
