如何在字典初始化时调用__set_item__？

class CustomDict(dict):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.__setitem__('key', 'value')

    def __setitem__(self, key, value):
        # 自定义的处理逻辑
        print(f"Setting key: {key}, value: {value}")
        super().__setitem__(key, value)

# 使用自定义的字典类进行初始化
my_dict = CustomDict()

Setting key: key, value: value
