python中类篇的参数问题

代码第10行不是已经提供了实参（China Kongfu,川菜）了吗，为什么错误中还显示Restaurant没有带参数

下图为论坛代码

__init__ 是两个下划线

是__init__两个下划线

class Restaurant:
    def __init__(self, _name, _type):
        self.restaurant_name = _name
        self.cuisine_type = _type

    def describe_restaurant(self):
        print(f"the restaurant's name is {self.restaurant_name}")

    def open_restaurant(self):
        print(f"the restaurant's type is {self.cuisine_type}")


restaurant = Restaurant('China Kongfu', '川菜')
restaurant.describe_restaurant()
restaurant.open_restaurant()

# the restaurant's name is China Kongfu
# the restaurant's type is 川菜
