1.封裝?

?

?

class phone:__voltage = 0.5def __keepsinglecore(self):print("單核運行")def callby5g(self):if self.__voltage >= 1:print("5g通話開啟")else:self.__keepsinglecore()print("不能開啟5g通話")p = phone()
p.callby5g()

?

2.繼承?

?

class phone:imei = Noneproducer = "aa"def call_by_4g(self):print("4g通話")class phone2024(phone):face_id = 1def call_by_5g(self):print("5g通話")p = phone2024()
print(p.producer)
p.call_by_4g()

?

?如果是多繼承并且有同名的，會以之前的為優先，之后的會被覆蓋

class phone:imei = Noneproducer = "aa"def call_by_4g(self):print("4g通話")class nfc:def read(self):print("nfc讀卡")class phone2024(phone,nfc):pass#用pass表示這里是空的p = phone2024()
print(p.producer)
p.call_by_4g()
p.read()
