Question 120

What is the expected behavior of the following code?

    Correct Answer: B

    The code will raise a TypeError. The method 'make' in class 'Super' does not return a value, which means it implicitly returns 'None'. Therefore, 'b.doit()' will return 'None'. When trying to add 'a.doit()' which returns '1' to 'None', Python will raise a TypeError as it cannot perform addition between an integer and NoneType.
