问题 I have a variable device='A/B/C/X1' that is commented out in another file. There can be multiple instances of the same device such as 'A/B/C/X1@1' , ..@2 and so on. All of these devices are commented out in another file with a prefix * . I want to remove the * but not affect similar devices like 'A/B/C/X**10**' . I tried using regex to simply substitute a pattern using the following line of code, but I'm getting an InvalidExpression error. line=re.sub('^*'+device+'@',device+'@',line) Please

问题 I have a loop running in the main() function of my program that looks as follows while True: data, addr = sock.recvfrom(MAX_MESS_LEN) thread.start_new_thread(message_handler, (data, addr,)) I would like to introduce functionality that allows me to perhaps hit 'q' to break out of the loop and end the program. I'm not sure how to do this since the program waits on the recvfrom() call until receiving a message. Is there a way to implement an interrupt key or keyboard event catcher or something?
