(3 points) A common programming operation is to swap or exchange the values of two variables. If the value of x is currently 43 and the value of y is 33 , swapping them will make x into 33 and y into 43 , Write a program named swap.py that allows the user to enter two int values. The program should store those values into variables and then swap the variables. Print the values of both variables before and after the slyap. You will receive full credit as long as your solution works, but try to do this using as few variables as possible. Example program run (underlined parts indicate what the user enters) Enter value for x:43 Enter value for y:33 Before swap: x=43,y=33 After swap: x=33,y=43
