I know this doesn't completely have to do with the lesson, but I need some help. I tried playing around with classes a bit, and for some reason when I try to change an inherited variable of a subclass, it wont work. Example:
class supClass:
def __init__(self, **info):
self.name = info.get("name", "...")
self.age = info.get("age", 100)
class sub(supClass):
age = 200
=-=-= Console =-=-=
p = sub()
p.age --> 100
The output is still 100. Please help. Sorry if this confused you.

7,410 PointsNot sure if this is exactly the right answer, as I haven't tried it myself, but I think this is occurring because you don't have a init method for your sub class. So when you create an object, it runs the init method from your supClass. If you create an init method in your sub class, I would imagine that would fix the problem.

6,952 Pointssub inherits __init__ from supClass because it doesn't have its own, so it's called when p is created, effectively in the same scope. The reason p gets 100 instead of 200 is that when it's set in an __init__ procedure, it's object-level instead of class-level and so takes precedence.
Defining __init__ (and overriding the version that would otherwise be inherited) in the subclass gives you what you want.
