存储短信

Question

我意识到这是一个问题，在这个论坛上已经提出了多个解决方案，但我写了一个代码并得到了一个我不理解的错误，所以这主要是我所做的事情。我在这里问。

这是我的代码：

from datetime import datetime

class SMSstore:
    store = []
    read = []
    unread =[]

    def addNewArrival(number,time,text):
        SMSstore.store.append(("From: {}, Recieved: {}, Msg: {}".format(number,time,text)))

    def messageCount():
        return print("Number of Messages in Inbox: {}".format(len(SMSstore.store)))

    def viewall():
      print(SMSstore.store)

    def getUnreadIndexes():
      for message in SMSstore.store:
            if message[0] == False:
                unread.append(self.__inbox.index(message))
      return unread

    def getMessage(i):
        SMSstore.read.append(len(SMSstore.store))
        print(SMSstore.store[i])

    def delete(i):
        try:
            del SMSstore.store[i]
        except IndexError:
            print("Index is out of range. Cannot delete")
    def clear():
        del SMSstore.store

time = datetime.now().strftime('%H:%M:%S')
myInbox = SMSstore()
myInbox.addNewArrival("1234567890",time,"What is your name?")
myInbox.addNewArrival("0987654321",time,"What is your quest?")
myInbox.viewall()
myInbox.msgcount()
myInbox.delete(i)
myInbox.clear()

我得到的错误是：

line 37, in <module>
TypeError: addNewArrival() takes exactly 3 arguments (4 given)

Answer 1

你需要把self作为一个类中所有方法的第一个arg。

示例：

def addNewArrival(self, number, time, text):
def messageCount(self):
def viewall(self):
