This dir() function returns the list of names in the current local scope. If supplied with an argument attempts to return a list of valid attributes for that object.
dir([object])Here,
Note: If the object has a method named __dir__(), this method will be called and must return the list of attributes. This allows objects that implement a custom __getattr__()or __getattribute__() function to customize the way dir() reports their attributes.
If the object does not provide __dir__(), the function tries its best to gather information from the object’s __dict__ attribute, if defined, and from its type object.
>>> class Class1:
... def __init__(self, name):
... self.name = name
