Greetings!
So the stdlib Enum has been around for a few years now. Has anyone
written an enum that either had types as members:
class Types(Enum):
Int = int
Str = str
or that had nested classes:
class Types(Enum):
class Contained(Enum):
circle = 1

is really seems to be the sticking point -- what should an Enum of Enums look
like? For example, should the above do
--> list(Colour)
[Colour.PrimaryColour <...>, Colour.SecondaryColour <...>]
or something else?
The only example I have seen so far of nested classes in an Enum is

erit from Enum:

class PrimaryColour(Enum):
RED = 1
GREEN = 2
BLUE = 3
OCTARINE = 8

Question:
Should `SomeClass` be an enum member? When would it be useful to have an
embedded class in an Enum be an enum member?
The only example I have seen so far of nested classes in an Enum is when folks want to make an Enum of Enums, and the
nested Enum should not it

Hi,
I'm currently writing a C extension module for python using the "raw" C-API. I
would like to be able to define "nested classes" like in the following python
code
class A:
class B:
class attributes because the statements bb=... and cc=...
are inside the class definition). It works, but perhaps that's not what
you want. If you want instance attributes instead, create them in
AA.__init__ by using self.bb=something
Nested classes provide no benefit here an
I have class structure as below. How can I create the following nested class
and its properties dynamically.
class AA(object):
class BB(object):
def setBB1(self, value):
##some code
def getBB1(self):
bb1 = #somecode
return bb1

Hello,
as an example of what I would like to achieve, think of a street
where each house has a door and a sign with a unique (per house)
number on it. I tried to model this like this:
class House(object):
class Door(object):
def __init__(self,color):
self.color=color

I'm experimenting with using Python for a small web interface, using

I use a small class hierarchy which uses inheritance and nested classes.
