multithreading - Python Print while waiting for input -

def receivedata(self):     while true:         data = self.soc.recv(1024)         if data != "" or data != '' or data != "":             sys.stdout.write("recv>> ")             sys.stdout.write(data)             sys.stdout.flush()             if data == "server shutdown":                 self.soc.close()         elif not data:             continue def senddata(self):     while true:         try:             sys.stdout.write("send>> ")             msg = sys.stdin.readline()             self.soc.send(msg)         except socket.error:             sys.stdout.write("socket connection timed out") 

this part of client code of python, , expect while waits user input, prints receives server.

however, client not print when waiting user input -- prints when has been entered user.

is there way change prints when waiting user input?

if program needs wait on 2 separate events (user input , incoming socket data), you'll have use threads, like:

recv_thread = threading.thread(target=receivedata) recv_thread.setdaemon(true) recv_thread.start() senddata() 

couple of things code:

• when socket.error encountered can other timeout.
• at 1 point need exit while loop senddata (when user input text? or) in case of exception.
• also add exception handling in receivedata

• if statement in receivedata not ok. replace to:

  if data:     ...if statements...
