Pythonic方式将多个类方法应用于对象列表

class Person:
    def __init__(self, name):
        self.name = name

    def say_hello(self):
        print(f"Hello, {self.name}!")

    def say_goodbye(self):
        print(f"Goodbye, {self.name}!")

people = [Person("Alice"), Person("Bob"), Person("Charlie")]

# 应用say_hello()方法
[say_hello_method(person) for person in people]

# 应用say_goodbye()方法
[say_goodbye_method(person) for person in people]

class Person:
    def __init__(self, name):
        self.name = name

    def say_hello(self):
        print(f"Hello, {self.name}!")

    def say_goodbye(self):
        print(f"Goodbye, {self.name}!")


def say_hello_method(person):
    getattr(person, "say_hello")()


def say_goodbye_method(person):
    getattr(person, "say_goodbye")()


people = [Person("Alice"), Person("Bob"), Person("Charlie")]

# 应用say_hello()方法
[say_hello_method(person) for person in people]

# 应用say_goodbye()方法
[say_goodbye_method(person) for person in people]
