return 0.5 (self.a + self.b) * self.h – Chase Jun 27 '20 at 03:01

When you're referencing class members, you need to use `self.a` and `self.b`. `a`, `b`, and `h` are scoped in self. – Alex Jun 27 '20 at 03:02

`self.a`, not `a`. Who does `a` belong to? `self`. – Mateen Ulhaq Jun 27 '20 at 03:02

If you are new to the language, at the very least you should check out the [official docs](https://docs.python.org/3/tutorial/classes.html) where this would have been revealed – juanpa.arrivillaga Jun 27 '20 at 03:03

That's right, it's not defined. You meant self.a, as well as the other two.
return 0.5 (self.a + self.b) * self.h
Though then you have another error: TypeError: 'float' object is not callable

So you are trying to access 'a', 'b' and 'h' values in the getArea method, you might want to change it to
def getArea(self):
return 0.5 (self.a + self.b) * self.h
