New improved version:
def submodule(f):
co = f.__code__
i = len(co.co_consts)
b = bytes([0x64, i, 0x83, 0x0, 0x53, 0x0])
f.__code__ = co.replace(
co_consts = co.co_consts + (locals,),
co_code = co.co_code[:-4] + b
)
return type(f.__name__, (), f())
@submodule
def Stuff():
I have no idea if this is a good idea, but Python already has modules to be
namespaces for a collection of functions and values.
And while a class decorator is *supposed* to return a class, it can, in
fact, return anything. So you can make a decorator that converts a class
definition to a module

That got me thinking, and I came up with this:
def submodule(f):
return type(f.__name__, (), f())

Well, IMHO the solution is quite more simple:
class Car:
def __init__(self):
self.state = "parking"
def move(self):
if self.state != "moving":
In Python 3 you can do this without any decorators.
The following works and produces the same output:
class AA:
def greet(A_instance):
print("Hello", A_instance.name)
class BB:
def greet(A_instance):
print("Hi", A_instance.name)
class A:
def __init__(self, state, name):

NOTE 1:
After writing this whole post, I realized that while you used @classmethod,
what you seem to really want is a fully @staticmethod class -- certainly
your example was a static method, and some other posters were talking about
static method (i.e. "it's bad style to have unused parameters in
I was just working on that, although I prefer staticmethod:
def allstatic(cls):
for key, value in cls.__dict__.items():
if not key.startswith('__'):
setattr(cls, key, staticmethod(value))
return cls
@allstatic
class C:
def foo(a, b):
print(f'{a}, {b}')
I think the OP would be happy with a decorator they can just copy-paste.
All it needs to do is go over the class dict and apply @classmethod to
every “normal” function. Probably skip under names.

Hi Irit,
In my case, the code structure is as below.
I'm writing a city traffic simulator which includes roads and cars.
Cars have different states, MovingCar, IdleCar, ParkingCar...
A car can move between different states and it keeps the same information.
My solution to this was,

I cannot answer for Alperen, but I commonly encounter this when writing
testing code: generally I use the format:
some_module.py
tests/test_some_module.py
where it is expected the filename to test a module is
"test_module_name.py". However, within that, I might want to namespace
based on the
Hi Alperen,
Why do you need a class at all rather than just a module with some functions?
