Hi All,
I have a question.
Let says I have the following two classes:
class Base(object):
__mylist__ = ["value1", "value2"]
def somemethod(self):
pass
class Derived(Base):
__mylist__ = ["value3", "value4"]
def anothermethod(self):
pass
what I would like to accomplish is that the class Derived has the member __mylist__ extended or merged as
["value1", "value2", "value3", "value4"].
Is there anyway I could accomplish this?
I was thinking on accomplishing this as follows:
class Derived(Base):
__mylist__ = Base.__mylist__ + ["value3", "value4"]
def anothermethod(self):
pass
Is there a better way? Perhaps a decorator?
This is already done the best (clearest) way I know of.
However, I'd like to point out two things:
1) they're not called class members, but class attributes. You have
class attributes and instance attributes.
2) dunder methods should only be used to fulfill special methods defined
by the language. If it's a public attribute, just leave off the
underscores entirely. And if it's private, put just one leading underscore.
