用Python模拟一个手机操作系统——手机联系人模块的实现

这次的项目稍微长一点，分成两篇文章来写
我们来简单的模拟一个手机操作系统

这里我们将项目分成了两个模块
分别是手机本体和手机联系人

本篇我们看一下手机联系人的模块

这里我们先定义饿了联系人类
然后我们开始构造初始类属性

def __init__(self, fname, lname, pnumber):
    self.fname = fname
    self.lname = lname
    self.pnumber = pnumber
    self.messages = []
    self.m_messages = 20

接下来是基础的获取和修改基础信息

def get_first_name(self):
    return self.fname

def get_last_name(self):
    return self.lname

def get_phone_number(self):
    return self.pnumber

def update_first_name(self, first_name):
    if first_name:
        self.fname = first_name
    else:
        return None

def update_last_name(self, last_name):
    if last_name:
        self.lname = last_name
    else:
        return None

def update_phone_number(self, number):
    if number:
        s_number = str(number)
        if 6 <= len(s_number) <= 14:
            if ' ' not in s_number and '+' not in s_number:
                self.pnumber = number
                return True
            else:
                return False
        else:
            return False
    else:
        number = ''
        return False

添加联系人

def add_chat_message(self, who_said_it, message):
    if len(self.messages) < self.m_messages:
        self.messages.append(who_said_it + ": " + message)
        return True
    else:
        messages_copy = []
        flag = 1
        while flag < self.max_messages:
            messages_copy.append(self.messages[flag])
            flag += 1
        self.messages = messages_copy
        self.messages.append(who_said_it + ':' + message)
        return True

清空联系人列表

def clear_chat_history(self):
    self.messages = []
    return True

获取最后添加联系人和获取最先添加的联系人

def get_last_message(self):
    return self.messages[-1] if self.messages else None

def get_oldest_message(self):
    return self.messages[0] if self.messages else None

将联系人列表拷贝一份

def create_copy(self):
    new_contact = dorrigo_contact(self.fname, self.lname, self.pnumber)
    new_contact.messages = self.messages
    return new_contact

完整的联系人模块代码如下：

class dorrigo_contact:

    def __init__(self, fname, lname, pnumber):
        self.fname = fname
        self.lname = lname
        self.pnumber = pnumber
        self.messages = []
        self.m_messages = 20

    def get_first_name(self):
        return self.fname

    def get_last_name(self):
        return self.lname

    def get_phone_number(self):
        return self.pnumber

    def update_first_name(self, first_name):
        if first_name:
            self.fname = first_name
        else:
            return None

    def update_last_name(self, last_name):
        if last_name:
            self.lname = last_name
        else:
            return None

    def update_phone_number(self, number):
        if number:
            s_number = str(number)
            if 6 <= len(s_number) <= 14:
                if ' ' not in s_number and '+' not in s_number:
                    self.pnumber = number
                    return True
                else:
                    return False
            else:
                return False
        else:
            number = ''
            return False

    def add_chat_message(self, who_said_it, message):
        if len(self.messages) < self.m_messages:
            self.messages.append(who_said_it + ": " + message)
            return True
        else:
            messages_copy = []
            flag = 1
            while flag < self.max_messages:
                messages_copy.append(self.messages[flag])
                flag += 1
            self.messages = messages_copy
            self.messages.append(who_said_it + ':' + message)
            return True

    def clear_chat_history(self):
        self.messages = []
        return True

    def get_last_message(self):
        return self.messages[-1] if self.messages else None

    def get_oldest_message(self):
        return self.messages[0] if self.messages else None

    def create_copy(self):
        new_contact = dorrigo_contact(self.fname, self.lname, self.pnumber)
        new_contact.messages = self.messages
        return new_contact
