英文:
Is vars() same as __dict__?
问题
vars() 是一个内置函数，返回类、模块或对象的 __dict__ 属性。但是，当我检查 vars(Person) is Person.__dict__ 时，它返回 False（Person 是类的名称）。
英文:
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 = nameself.age = agevars(Person) is Person.__dict__ # False</details># 答案1**得分**: 4Classes create a new mappingproxy on every `__dict__` access. You would see the exact same results from `Person.__dict__ is Person.__dict__`.<details><summary>英文:</summary>Classes create a new mappingproxy on every `__dict__` access.
