class Restaurant():

def _init_(self, restaurant_name, cuisine_tpye):
    self.restaurant_name = restaurant_name
    self.cuisine_tpye = cuisine_tpye
   

my_restaurant = Restaurant("KFC","fast food")

提示错误

TypeError Traceback (most recent call last)
<ipython-input-3-c7d16ceda31f> in <module>

  5         self.cuisine_tpye = cuisine_tpye
  6 

----> 7 my_restaurant = Restaurant("KFC","fast food")

TypeError: Restaurant() takes no arguments

Answer 1

定义类为啥要加括号？要么括号里面写（object）（python2需要），要么去掉括号：

class Restaurant(object):
    pass

或者：

class Restaurant:
    pass
