Shouldn’t field be undefined on line 50? It was my understanding that inner nested classes did not have visibility to outer classes, as I ran into on line 65… Just seems kind of inconsistent and I would love to have a better understanding of the outer nested classes visibility to avoid any confusion in the future.

Answer
I’ve write very simplified example:
class A:
class B:
def __init__(self):
print(A)
class C:
class D:
def __init__(self):
print(A)
A.B()
A.C.D()
A().C().D()
And class A is available as in inner as in inner inner class.
By initializing the levels after defining the game field rather than initializing the levels in the game field definition we are able to avoid the unresolved name error. See modified code.
