Can you have a class inside a class?

Question

For example:
class Dog:
def __init__(self, legs, teeth, Fur):
self.legs = legs
self.teeth = teeth
class Fur:
def __init__(self, color, length):
self.color = color
self.length = length

then create Rusty:

Rusty = Dog(4, "dull", Fur("brown", "short"))
print(Rusty.Fur.color)

I don't actually think that this code will run, but you get the idea...

Answer 1

was my syntax close? it does not run.
