多重继承
在本练习中,您将通过创建一个名为 Smartphone 的新类来练习实现多重继承。
下面给出了 Computer 和 Telephone 两个类的定义,创建 Smartphone 类时会用到它们。请仔细阅读这两个类!
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}")

通过完成这段示例代码来试试这个练习。
# Define a Smartphone class that inherits from Computer and
# Telephone, and takes parameters brand, phone_number, and
# music_app
class ____(____, ____):
def __init__(self, ____, ____, ____):
# Call the contructor for the Computer and Telephone
# class, define the music_app instance-level attribute
____.__init__(self, brand)
Telephone.__init__(self, ____)
self.music_app = ____
