這是一個基本問題。我正在嘗試以下代碼：class SMS_store:

def __init__(self):

self=[] #probably something is wrong here

def add_new_arrival(self,from_number,time_arrived,text_of_SMS):

self.append([False,from_number,time_arrived,text_of_SMS]) #append list to self list

self[len(self)-1]=tuple(self[len(self)-1])

def message_count(self):

return len(self)

my_inbox=SMS_store()

my_inbox.add_new_arrival('01234','9:37 AM','How are you?')

但我得到了以下錯誤：>>>

Traceback (most recent call last):

File "C:\Users\Arnob\Desktop\New Text Document.py", line 15, in

my_inbox.add_new_arrival('01234','9:37 AM','How are you?')

File "C:\Users\Arnob\Desktop\New Text Document.py", line 8, in add_new_arrival

self.append([False,from_number,time_arrived,text_of_SMS]) #append list to self list

AttributeError: 'SMS_store' object has no attribute 'append'

>>>

我的密碼怎么了？
