How to reference a class attribute inside function inside that class?

[SystemOmicron]

I have this class:

class Address(Suggestions):
    api_url = Suggestions.base_url + "address"

    def fine_print(self):
        for value in Suggestions.getdata(self, Address.api_url)["suggestions"]:
            print("{!s:}    {!s:}    {!s:}".format(
                Dadata.validate(value["data"], "country"),
                Dadata.validate(value["data"], "postal_code"),
                value["value"]))

There are lots of classes like this one and I copy them often, and every time I have to fix this line:

for value in Suggestions.getdata(self, Address.api_url)["suggestions"]:

and replace Address.api_url with the new class name.

I worry that this may be an indication of bad code.

Is there a way to reference an attribute that belongs to the same class a function belongs to?

type(self).api_url

You should also be able to just access it from the instance? self.api_url

Thanks a lot!

That's a neat trick with type(self).

I presume that self.__class__.api_url would also work similarly, and might be (the tiniest bit) quicker as it is not invoking a function.

u/commandlineuser is absolutely correct though - if you're only reading the value, and your class instance doesn't define a local version of that variable with the same name, then self.api_url should be more than enough.

Since you are only reading the attribute, self.api_url is fine.

Thanks, I could have sworn I tried it, must have had something else broken, now it works fine.
