Python名稱錯誤：名稱'名稱'未定義

Question

我正在做python中的套接字編程和查找消息。這是我的代碼.....

import socket 

    def Main(): 
      host = '127.0.0.1' 
      port = 5000 
      s = socket.socket() 
      s.bind((host,port)) 
      s.listen(2) 
      c, addr = s.accept() 
      print "Connecton 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() 
      c.close 

    if _name_ == '_main_': 
     Main() 

，我收到類似

'File "tcpserver.py", line 21, in if name == 'main': NameError: name 'name' is not defined'

Answer 1

的消息應該是：

if __name__ == '__main__':

Answer 2

那麼，它應該是：

if __name__ == '__main__': 
    Main() 

With兩個（2）下劃線。
