Can anyone explain why when I create a class in Python for example:
class My:
and when I print(dir(python)) it returns a list of functions and attributes in which there is a __weakref__ method,
so my questions is from where did this method appear if the class that I create inherits from object class which doesn't have this method
These methods (the ones starting with double underscore) are called dunder methods.See more and this weakref
These are usually called by a wrapper function. For example, the dict() function calls the __dict__() method.
we won’t be needing the double underscore prefixed methods, so we can filter them using the below snippet:
method_list = [method for method in dir(My) if not method.startswith('__')]
print(method_list)
Output:
[]
