NameError：名稱'記錄'未定義。 Python 3

Question

我一直在嘗試一切，我可以運行此代碼，但我無法弄清楚是什麼問題。這是一個服務器/客戶端聊天程序在python 3中。我得到的錯誤是：

Traceback (most recent call last): 
    File "/home/nate/Desktop/soc_chat/server_soc.py", line 48,<module> 
    handler = ClientHandler(client, record) 
NameError: name 'record' is not defined 

我不知道如何解決此問題。任何幫助都會很棒。我在Ubuntu上，安裝了python 3。我已經嘗試在終端中運行代碼爲'python3 myFile.py'，而不是'python myFile.py'，以確保它不會像python 2那樣運行它。正如我所說的，任何幫助都將不勝感激。

下面的代碼（服務器端）：

from socket import * 
from codecs import decode 
from chatrecord import ChatRecord 
from threading import Thread 
from time import ctime 

class ClientHandler(Thread): 

    def __init__(self, client, record): 
     Thread.__init__(self) 
     self._client = client 
     self._record = record 

    def run(self): 
     self._client.send(bytes('Welcome', CODE)) 
     self._name = decode(self._client.recv(BUFSIZE), CODE) 
     self._client.send(bytes(str(self._record), CODE)) 
     while True: 
      message = decode(self._client.recv(BUFSIZE), CODE) 
      if not message: 
       print('Client disconnected') 
       self._client.close() 
       break 
      else: 
       message = self._name + '' + \ 
          ctime() + '\n' + message 
       self._record.add(message) 
       self._client.send(bytes(str(self._record), CODE)) 


HOST = 'localhost' 
PORT = 5000 
BUFSIZE = 1024 
ADDRESS = (HOST, PORT) 
CODE = 'ascii' 
server = socket(AF_INET, SOCK_STREAM) 
server.bind(ADDRESS) 
server.listen(5) 

while True: 
    print('Waiting for connection...') 
    client, address = server.accept() 
    print('...connected from:', address) 
    handler = ClientHandler(client, record) 
    handler.start() 

代碼（客戶端）：

from socket import * 
from codecs import decode 

HOST = 'localhost' 
PORT = 5000 
BUFSIZE = 1024 
ADDRESS = (HOST, PORT) 
CODE = 'ascii' 
server = socket(AF_INET, SOCK_STREAM) 
server.connect(ADDRESS) 
print(decode(server.recv(BUFSIZE), CODE)) 
name = input('Enter your name: ') 
server.send(bytes(name, CODE)) 

while True: 
    record = decode(server.recv(BUFSIZE), CODE) 
    if not record: 
     print('server disconnected') 
     break 
     print(record) 
     message = input('> ') 
    if not message: 
     print('Server disconnected') 
     break 
     server.send(bytes(message, CODE)) 
server.close() 

代碼（chatrecord.py）

class ChatRecord(object): 

    def __init__(self): 
     self.data = [] 

    def add(self, s): 
     self.data.appent(s) 

    def __str__(self): 
     if len(self.data) == 0: 
      return 'No messages yet!' 
     else: 
      return '\n'.join(self.data) 

Answer 1

我要去走出一條肢體，說你忘了以下行：

record = ChatRecord() 

您可以導入類，但從不在服務器端代碼中使用它。

請注意，您在ChatRecord.add()方法拼錯list.append()：

def add(self, s): 
    self.data.appent(s) 
    #   ^
