使用类和方法的Python SMS存储程序-是否已查看状态

谢谢你看这个

这就是我需要做的：

from datetime import datetime

class sms_store:
    store = []
    read = []
def add_new_arrival(self,number,time,text):
    sms_store.read.append(len(sms_store.store))
    sms_store.store.append(("From: {}, Recieved: {}, Msg: {}".format(number,time,text)))
def delete(self,i):
    try:
        del sms_store.store[i]
    except IndexError:
        print("Index is out of range. Cannot delete")
def message_count(self):
    return print("Amt of messages in inbox: {}".format(len(sms_store.store)))
def viewall(self):
    print(sms_store.store)
def get_unread_indexes(self):
    #### ###################################I need help for this method.
def get_message(self,i)
    print(sms_store.store[i])
### tests ####
time = datetime.now().strftime('%H:%M:%S')
my_inbox = sms_store() #instantiate an object 'store' for class
my_inbox.add_new_arrival("12345",time,"Hello how are you?") #instance of store object
my_inbox.add_new_arrival("1111111",time,"BYE BYE BYE")
my_inbox.viewall()
my_inbox.msgcount()

添加新邮件时，其已查看状态设置为False

my_inbox.add_new_arrival()

返回所有尚未查看的SMS消息的索引列表

my_inbox.get_unread_indexes()

返回信息[i] 同时将其状态更改为“已查看”。 如果在位置i没有消息，则返回None

请在上述方法上帮助我

非常感谢你

为什么不在类中添加另一个名为“未读”的列表呢。更改

add\u new\u arrival

将邮件添加到未读状态

然后在

get_message

方法下，将指定的消息从未读移动到已读

---

最后，你的

get_unread

方法只列出了未读列表的索引。

嗨，我对你的代码做了一些调整，我想我以前在《如何像计算机科学家一样思考》一书中做过，希望它对你有用

my_inbox.get_message(i)**

及

然后
