我被告知了几个定义,在维基百科上看,但作为Java的初学者,我仍然不确定它的含义.有流利的Java和白痴吗？

以下代码给出了一个未定义的全局名称错误,但据我所知,该名称已定义.我是Python的新手,这是一个范围问题吗？

import os, socket
from threading import Thread

class serv:
    def __init__(self):
        self.socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        self.socket.bind(('', 443))

    def run(self):
        self.socket.listen(10)
        print "Listening"
        self.conn, self.addr = self.socket.accept()
        try:
            Thread(target=clientThread, args=(self.conn,)).start()
        except Exception, errtxt:
            print errtxt

    def exit(self):
        print "Disconnected"
        self.conn.close()

    def clientThread(conn):
        print "Connected"
        while 1:
            conn.send("Hello, worlds!\n")

S = serv()
S.run()

具体错误是

global name 'clientThread' is not defined 

我正在尝试用Python编写一个简单的网络服务器,不幸的是,我正陷入让函数工作的简单障碍!

import os, socket

class serv:
    def __init__(self):
        self.host
        self.port = 'localhost', 58008
        self.socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.socket.bind((self.host, self.port)

    def send(self, msg):
        self.conn.send(msg + end)

    def run(self):
        self.socket.listen(1)
        self.conn
        self.addr = self.socket.accept()
        send(self, msg="Hello, world")

S = serv()
S.run()

此代码在函数调用send上给出以下错误:

File "server.py", line 10
def send(self, msg):
  ^
SyntaxError: invalid syntax

如果它有帮助(我确定它不会),我在使用Adafruit WebIDE的Raspberry Pi上做这个.
