Tutorial on using the join method in Python thread

join method: blocks a thread until it completes execution

So  , you can add a timeout operation to join, join([timeout]), and when the set time is exceeded, the thread is no longer blocked

Another consequence of jion plus is that the child thread is bound to the main thread at 1 and does not start executing the child thread until the child thread has finished running.

The code has join:
