Manual
Return the __dict__ attribute for a module, class, instance, or any other object with a __dict__ attribute.
Objects such as modules and instances have an updateable __dict__ attribute; however, other objects may have write restrictions on their __dict__ attributes (for example, classes use a types.MappingProxyType to prevent direct dictionary updates).
Without an argument, vars() acts like locals(). Note, the locals dictionary is only useful for reads since updates to the locals dictionary are ignored.
直译
返回模块、类、实例或任意其他有__dict__属性对象的__dict__属性,无论如何,其他对象都有可能在它们的__dict__属性写入了约束(例如:某个使用types.MappingProxyType的类会阻止直接更新字典)。
无参数时,vars()与locals()表现相同,注意局部字典只在读取有用处,当更新局部字典是将会被忽略。
实例
>>> vars()
{'__builtins__': <module 'builtins' (built-in)>, '__name__': '__main__', '__loader__': <class '_frozen_importlib.BuiltinImporter'>, '__package__': None, '__doc__': None, '__spec__': None}
>>> class 优快云:
def csdner(self, s):
print('Hello ',s)
>>> vars(优快云)
mappingproxy({'__weakref__': <attribute '__weakref__' of '优快云' objects>, '__dict__': <attribute '__dict__' of '优快云' objects>, 'csdner': <function 优快云.csdner at 0x000001FEEB257840>, '__module__': '__main__', '__doc__': None})
