I need help witht the following problem, thank you for your help!

You are to write a program in either Java, C++, Python that takes two sets of up to 5 symbols (letters, numbers or any characters) and prints the cartesian product of the two sets. The program should allow the user to enter the characters for each set and the output should, consist of the name of each set followed by the characters and on the following line print the cartesian product. Example: A {1,3,4} X B {3,?,D} = {(1,3),(1,?),(1,D),(3,3),(3,?), (3,D,(*,3),(*.?),(*,D)} or E {2,3,5,7} X F(5,6} = {(2,5),(2,6),(3,5),(3,6),(5,5),(5,6), (7,5),(7,6)}
