在此之前，我几乎没有做过任何编程，所以我提前为我的代码的质量道歉。在另一个进程中打开python函数
我遇到的问题是我有一个图形用户界面，我需要打开一个服务器来接收互联网流量，但如果我尝试在新的过程中打开它，我会得到一个关于未定义名称的错误（即使它可以正常工作，但如果我将服务器作为常规功能打开而不是新进程）。有趣的是，即使出现错误，GUI仍然会打开。
我会在代码后面粘贴错误消息。
预先感谢您。

编辑：
我想建议在第一个回复，但它仍然提供了一个错误

这里是tcpServer.py
import socket
import netifaces as ni
def start(self, _netint):
host = ni.ifaddresses(self._netint)[ni.AF_INET6][0]['addr']
port = 5000
s = socket.socket(socket.AF_INET6)
s.bind((host, port))
s.listen(1)
c, addr = s.accept()
print "Connection from: " + str(addr)
while True:
data = c.recv(1024)
if not data:
break
print "from connected user: " + str(data)
data = str(data).upper()
print "sending: " + str(data)
c.send(data)
c.close()
if __name__ == '__main__':
start()
代码这里用于tcpClient.py
import socket
def startclient(targetip):
host = targetip
port = 5000
s = socket.socket(socket.AF_INET6)
s.connect((host,port))
message = raw_input('Send message: ')
while message != 'q':
s.send(message)
data = s.recv(1024)
print 'Recieved from server: ' + str(data)
message = raw_input('Send message: ')
s.close()
if __name__ == '__main__':
startclient()
请注意，我的服务器和客户端程序仅用于测试。
