Using inheritance in python

Question

this is my homework assignment, I saw it posted on the website before, but it looks like it was unsolved and I got a different error message than a person asking that questi

Answer 1

The error is pretty clear. salary is not defined in the __init__ method of Executive.

You used wage as an argument to __init__, but salary when calling __init__ of your parent class, so you should stick to one variable name:

class Executive(Employee):
    def __init__(self, name, salary, yearlyBonus):
        Employee.__init__(self, name, salary) 

Also, you can get around typing all of those parameters in each time by using *args:

class Executive(Employee):
    def __init__(self, *args, yearlyBonus):
        super(Executive, self).__init__(*args)

Use super() instead of calling the parent class's __init__ method. It makes multiple inheritance a bit easier.
