The following Python code deals with parameter passing. What is printed out by each print statement when function Main is called? Each print statement is numbered 1 - 10. def Function1 (W, X=5): return W+X def Function2 (Z, W, Y=4): return Function1(Z, W+Y) def Function3 (X, Y=2, Z=3): return Function2(Y, Z, X) def Main(): print Function1 (10, 2) # 1 print Function1 (6) # 2 print Function2 (4, 3, 1) # 3 print Function2 (7, 3) # 4 print Function2 (-4, 5) # 5 print Function3 (8) # 6 print Function3 (4, 7) # 7 print Function3 (1, 3, 5) # 8 print Function2 (2, Function1(6)) # 9 print Function3 (Function1(9)) # 10 return
