Re: [Tutor] While Loop Help

While Alan has given you a far better solution, I feel someone should mention the break statement as you will likely come across it a lot, and it is quite an important flow control statement. You could add a break statement to the else which would break out of the while loop.

Re: [Tutor] While Loop and Threads

Thanks! I'll have a side question. If I implement this idea to my case, threadWorker() would look like this: def threadWorker(_arg1, _arg2): print(Starting worker thread with args: %s, %s % (_arg1, _arg2)) while g_threadStop.is_set() == False: ## here comes a for loop:

So if I understand this correctly, you want to start a thread and then stop it after a certain time period? Here's an adapted example that includes a timer. (I believe in learning by example where possible) With that said, if it were my code going into production I'd move the timer logic out of

Multi-threading takes practice! Are you using an event object to signal the thread should exit? I'm guessing you're just using a bool which is why it does not work. See: https://docs.python.org/3.4/library/threading.html#event-objects I'm very short on time and the moment and therefore can't
