如何在Python中检查局部和全局作用域以及覆盖类中的变量？

class MyClass:
    class_variable = "I am a class variable"

    def __init__(self):
        self.instance_variable = "I am an instance variable"

    def check_scopes(self):
        local_variable = "I am a local variable"
        print("Local variables:", locals())
        print("Global variables:", globals())
        print("Class variable:", self.class_variable)
        print("Instance variable:", self.instance_variable)

my_object = MyClass()
my_object.check_scopes()

Local variables: {'self': <__main__.MyClass object at 0x000001234567890>, 'local_variable': 'I am a local variable'}
Global variables: {'__name__': '__main__', '__doc__': None, '__package__': None, '__loader__': <class '_frozen_importlib.BuiltinImporter'>, '__spec__': None, '__annotations__': {}, '__builtins__': <module 'builtins' (built-in)>, 'MyClass': <class '__main__.MyClass'>, 'my_object': <__main__.MyClass object at 0x000001234567890>}
Class variable: I am a class variable
Instance variable: I am an instance variable
