用python写一个好友管理系统

以下是一个简单的好友管理系统的参考代码，使用Python语言编写：

class Friend:
    def __init__(self, name, age, gender, phone):
        self.name = name
        self.age = age
        self.gender = gender
        self.phone = phone

class FriendManagementSystem:
    def __init__(self):
        self.friends = []

    # 添加好友
    def add_friend(self, friend):
        self.friends.append(friend)

    # 删除好友
    def remove_friend(self, name):
        for friend in self.friends:
            if friend.name == name:
                self.friends.remove(friend)
                return True
        return False

    # 查找好友
    def find_friend(self, name):
        for friend in self.friends:
            if friend.name == name:
                return friend
        return None

    # 显示所有好友
    def show_all_friends(self):
        for friend in self.friends:
            print(f"Name: {friend.name}, Age: {friend.age}, Gender: {friend.gender}, Phone: {friend.phone}")

# 测试代码
if __name__ == "__main__":
    # 创建好友管理系统对象
    fms = FriendManagementSystem()

    # 添加好友
    f1 = Friend("Tom", 18, "Male", "123456789")
    f2 = Friend("Lucy", 19, "Female", "987654321")
    fms.add_friend(f1)
    fms.add_friend(f2)

    # 查找好友
    f = fms.find_friend("Tom")
    if f:
        print(f"Find friend: Name: {f.name}, Age: {f.age}, Gender: {f.gender}, Phone: {f.phone}")
    else:
        print("Not found friend.")

    # 删除好友
    result = fms.remove_friend("Tom")
    if result:
        print("Remove friend success.")
    else:
        print("Remove friend fail.")

    # 显示所有好友
    fms.show_all_friends()

这个好友管理系统可以添加、删除、查找和显示所有好友。你可以根据自己的需求进行修改和扩展。
