Apr 11, 2014 · The thread cannot last longer than time set by the duration variable. How can I make it so after the length set by duration, the threads stop. def main(): t1 = threading.Thread(target=thread1, args=1) t2 = threading.Thread(target=thread2, args=2) time.sleep(duration) #the threads must be terminated after this sleep

In this article, we’ll learn how we can end a long-running execution after a certain time. We’ll explore the various solutions to this problem. Also, we’ll cover some of their pitfalls.
Imagine that we’re processing a bunch of items in a loop, such as some details of the product items in an e-commerce application, but that it may not be necessary to complete all the items. In fact, we’d want to process only up to a certain time, and after that, we want to stop the execution and show whatever the list has processed up to that time....
Here, we’ll use a separate thread to perform the long-running operations. The main thread will send an interrupt signal to the worker thread on timeout. If the worker thread is still alive, it’ll catch the signal and stop its execution. If the worker finishes before the timeout, it’ll have no impact on the worker thread. Let’s take a look at the wo...
There’s no guarantee that the execution is stopped after a certain time. The main reason is that not all blocking methods are interruptible. In fact, there are only a few well-defined methods that are interruptible. So, if a thread is interrupted and a flag is set, nothing else will happen until it reaches one of these interruptible methods. For ex...
In the previous section, we highlighted the importance of having interruptible methods to stop the execution as soon as possible. Therefore, our code needs to consider this expectation from a design perspective. Imagine we have a long-running task to execute, and we need to make sure it doesn’t take more time than the specified. Also, suppose the t...
In this tutorial, we’ve learned various techniques for stopping the execution after a given time, along with the pros and cons of each. The complete source code can be found over on GitHub.
Aug 9, 2024 · time.sleep(1) stop_event = threading.Event() thread = threading.Thread(target=infinite_loop, args=(stop_event,)) thread.start() # To stop the thread time.sleep(5) stop_event.set() thread.join() How to Make a Thread Wait in Python? To make a thread wait, you can use time.sleep(duration) for a simple pause, or Event.wait(timeout) if the wait ...
Sep 20, 2021 · A thread is automatically destroyed when the run() method has completed. But it might be required to kill/stop a thread before it has completed its life cycle. Previously, methods suspend(), resume() and stop() were used to manage the execution of threads. But these methods were deprecated by Java 2 because they could result in system failures.
Jan 8, 2024 · Let’s create a class called InterruptThread to use the interrupt() method in a running thread. When a thread is interrupted, it sets the interrupt flag of the thread, indicating that it has been requested to stop. If the thread gets an interrupt signal, it stops the while loop scope in the program:
Nov 15, 2024 · Method 3: Setting Threads as Daemon. Setting a thread as a daemon allows the main program to exit even if the thread is still running. By marking a thread as daemon, it will be terminated automatically when the main program exits, providing a way to stop the thread indirectly.
