Python Multi-Threading usage

Recently in the reptile, often use multi-threading. Here to summarize my multi-threaded usage habits, easy to access

1. Create a semaphore:

Mutex=threading. Lock ()

2. Signal Lock and release

# critical section mutex.release ()

3. Multithreading creation and startup

 for  in range (0,threadnum,1):            tmp_scan=myThread ()            Tmp_scan.setBar.connect ( Self.setprocessbar)            tmp_scan.setIp.connect (SELF.NOWIP)            Tmp_scan.setdaemon (True)            threads.append (tmp _scan)print  len (threads) for in Threads:           Thread.Start ()
