Python docs for None:Note that Python classes can override getattr and make things that look like properties but are not in__dict__. There's also the builtin functions vars() and dir() which are different in subtle ways. And __slots__ can replace __dict__ in some unusual classes. Objects are complicated in Python.The self-method works basically in the same way. To understand this better let’s take an example. myObject.myMethod(arg1, arg2), Python automatically transform it into myClass.myMethod(myObject, arg1, arg2).

Mar 8, 2024 · To get attributes of an object in Python, you can use the built-in dir function. To print object attributes, you need to iterate over the output of the dir function and use the getattr function to get the values of the attributes. Here are two code examples: class MyClass: def __init__(self, foo, bar): self.foo = foo. Python types are ordinary objects just like anything else (everything is an object). Being a type or an instance is a matter of the object's semantics, a role that it plays.
