Answer

In the above function definition, the line print("the answer is", x + y + z) is placed after the return statement. In python, once a return statement is encountered, the function exits immediately, and any subsequent code in the function is not executed. Therefore, the print statement will never be executed.

Predict the output of the following code :

a = 10
y = 5
def myfunc(): 
    y = a
    a = 2
    print("y =", y, "a =", a) 
    print("a + y =", a + y) 
    return a + y
print("y =", y, "a =", a)
print(myfunc())  
print("y =", y, "a =", a)
