多重繼承
在這個練習中,你將透過建立一個名為 Smartphone 的新類別來練習實作多重繼承。
下面提供了 Computer 與 Telephone 類別的定義,之後會用來建立 Smartphone 類別。請仔細查看這兩個類別!
class Computer:
def __init__(self, brand):
self.brand = brand
def browse_internet(self):
print(f"Using {self.brand}'s default internet browser.")
class Telephone:
def __init__(self, phone_number):
self.phone_number = phone_number
def make_call(self, recipient):
print(f"Calling {recipient} from {self.phone_number}")
