我有个问题。在使用 python 的 oops 中， super 可以访问方法或构造函数，但不能访问属性。这是为什么？？

class Phone:

  def __init__(self, price, brand, camera):
    print ("Inside phone constructor")
    self.__price = price
    self.brand = brand
    self.camera = camera

def buy(self):
    print ("Buying a phone")

def return_phone(self):
    print ("Returning a phone")

class FeaturePhone(Phone):
    pass

class SmartPhone(Phone):
    def __init__(self, price, brand, camera, os, ram):
       super().__init__(price, brand, camera)
       self.os = os
      self.ram = ram
      print ("Inside smartphone constructor")

    def buy(self):
      print(super().camera) #Error
      print ("Buying a smartphone")

s=SmartPhone(20000, "Samsung", 12, "Android", 2)

print(s.buy()) #error
print(s.brand) …
