Python Method Types Recap & Review

Sorry … digestible.

Im sorry man, but I didnt find good information from this tutorial. Perhaps more and different use cases. I would have preferred a longer tutorial if it meant more and clear guidance on this topic.

Thanks Dan, but have to agree with others. The links from stackoverflow have some good information, but a couple solid examples in the tutorial itself would have been preferable.

I found this example helpful: stackabuse.com/pythons-classmethod-and-staticmethod-explained/

Excellent !

Good but “too compact”!

Here is a bit of a deeper dive on this subject matter that still involves pizza (found via one of Dan’s stackoverflow posts linked above):

julien.danjou.info/guide-python-static-class-abstract-methods/

@Mark Walle, thanks for link, that article explains about bounded & unbounded methods which gave me further understanding into the python way. One thing I wonder is does a method have to be either a class/cls method, a bound/self method, a static method or an abstract method…there are no other options for it to be just a method?

Thank you so much!!! I have one question though: when we call @classmethod like Pizza.margherita(), does it mean we have created instance of class or object?

Thanks

Hi @ephremworkeye. Is it correct that you’re thinking of a @classmethod called margherita() that’s part of the Pizza class:

class Pizza:

    @classmethod
    def margherita(cls):
        return "It's a pi'zza!"

This toy implementation doesn’t make much sense as a @classmethod, considering that the cls argument isn’t used in the body of the method. But since that’s not the point of your question, we can let it slide :)

So if you’re calling a @classmethod called margherita() that’s part of the Pizza class, then you can get the following output:

>>> Pizza.margherita()
"It's a pi'zza!"

>>> Pizza.margherita() == Pizza().margherita()
True

>>> Pizza.margherita
<bound method Pizza.margherita of <class '__main__.Pizza'>>

Where do you think the @classmethod belongs to when you look at this output, and what’s your interpretation of the results? Can you come up with another test that might help answer your question?

@ephremworkeye instance of the class.
