defining a method that could be used as instance or static method

[Sam]

Hello

I would like to implement some kind of comparator, that could be
called as instance method, or static method. Here is a trivial pseudo
code of what I would like to execute
.... def __init__(self, value):
.... self.value = value
.... def comp(self, compValue):
.... return self.value == compValue.valueTrue

This is actually achieved by MyClass, how could implement it in order
to accept:
False

I would really appreciate a pointer or a way to complete MyClass in
order to fulfill my requirements. Thank you for your attention.

Did you try that it doesn't work? because it should. Whenever you do

instance.method(arg, ..)

you can as well do

Class.method(instance, arg, ...)

so your requirement should be met by comp already.

No... -_- I kept on trying things @staticmethod.
Thanks for your hint, it works fine!
