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
