面向对象的python中的嵌套类

class OuterClass:
    @staticmethod
    def outer_method():
        print("This is the outer method.")

    class StaticNestedClass:
        @staticmethod
        def nested_method():
            print("This is the nested method.")

# 访问静态嵌套类
OuterClass.StaticNestedClass.nested_method()

class OuterClass:
    def __init__(self):
        self.message = "Hello, world!"

    def outer_method(self):
        print("This is the outer method.")

    class InnerClass:
        def inner_method(self, outer):
            print("This is the inner method.")
            print(outer.message)

# 创建外部类对象
outer_obj = OuterClass()
# 创建非静态嵌套类对象
inner_obj = outer_obj.InnerClass()
# 调用非静态嵌套类方法
inner_obj.inner_method(outer_obj)
