NameError: name 'record' is not defined. Python 3

Question

我一直在尽我所能运行这段代码，但我无法弄清楚问题出在哪里。这是 python 中的一个 server/client 聊天程序 3. 我得到的错误是：

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

我不确定如何解决这个问题。任何帮助都会很棒。我在 ubuntu，安装了 python 3。我已经尝试在终端中运行将代码设置为 'python3 myFile.py' 而不是 'python myFile.py' 以确保它不会尝试将其运行设置为 python 2。正如我所说，任何帮助将不胜感激。

这是代码（服务器端）：

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()

代码（客户端）：

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()

代码(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)

我要冒险说你忘了下面这句话：

record = ChatRecord()

您导入 class 但从未在服务器端代码中使用它。

请注意，您在 ChatRecord.add() 方法中拼错了 list.append()：

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