Is vars() same as __dict__?

Question

I read that vars() is a built-in that returns the __dict__ attribute of class, module or object. But when I checked for vars(Person) is Person.__dict__, it returned False(Person is the name of class).

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

vars(Person) is Person.__dict__  # False

Answer 1

Classes create a new mappingproxy on every __dict__ access. You would see the exact same results from Person.__dict__ is Person.__dict__.
