python编写简单的朋友圈系统

好的，下面是一个简单的Python朋友圈系统的实现：

class Friend:
    def __init__(self, name):
        self.name = name
        self.posts = []

    def add_post(self, post):
        self.posts.append(post)

    def view_posts(self):
        for post in self.posts:
            print(post)

class Post:
    def __init__(self, content):
        self.content = content

    def __str__(self):
        return self.content

class FriendCircle:
    def __init__(self):
        self.friends = {}

    def add_friend(self, friend):
        self.friends[friend.name] = friend

    def add_post(self, friend_name, post):
        self.friends[friend_name].add_post(post)

    def view_posts(self, friend_name):
        self.friends[friend_name].view_posts()

使用方法：

# 创建朋友圈
fc = FriendCircle()

# 添加好友
alice = Friend("Alice")
bob = Friend("Bob")
fc.add_friend(alice)
fc.add_friend(bob)

# 发布动态
alice.add_post(Post("Hello, world!"))
bob.add_post(Post("I love Python!"))
alice.add_post(Post("Today is a beautiful day."))
bob.add_post(Post("I'm learning machine learning."))

# 查看动态
fc.view_posts("Alice")
fc.view_posts("Bob")

输出结果：

Hello, world!
Today is a beautiful day.
I love Python!
I'm learning machine learning.
