How do i use magic methods from another class?

Question

So I'm trying to use a magic method from one class in another class that inherits that class. basically what im trying to do below...

class Class1: def __magicmethod__(self, arg1, arg2): #blah blah class Class2(Class1): def func1(self, x, y): #what do type here to use the magic method???

thank you, I'm really confused about his

You dont call them directly - you call the wrapping method that will call the magic method. Example:__eq__ => == — balderman

Just call it directly: c = Class1(); c.__magicmethod__(x, y) — quamrana

@quamrana is there another way to write it like magicmethod( ...)? — Zypher100

It depends on the actual magic method. You should look up a list of them. Please update your question with a couple of concrete methods you are interested in. — quamrana

Just to transform both comments to a self-contained answer: If __magicmethod__ is one of the well-known ones with associated operator (like __eq__ is, simply use the operator to access that. If not, simply "call it directly":

class Class1: def __eq__(self, other): print(f"== from {self} with {other} here!") def __magicmethod__(self, arg1, arg2): print(f"{self}({arg1}, {arg2})") class Class2(Class1): def eq(self, other): self == other def func1(self, x, y): self.__magicmethod__(x, y)

And then use like:

>> c2 = Class2() >>> c2.func1("x", "y") <__main__.Class2 object at 0x0000021B8694A1F0>(x, y) >>> c2 == "foo" == from <__main__.Class2 object at 0x0000021B8694A1F0> with foo here! >>> c2.eq("foo") # same as before, but through your own method

Nothing special really.
