Multithreading in python.

Then whenever you want the thread stopped (like from your UI), just call on it: pinger_instance.kill.set () and you're done. Keep in mind, tho, that it will take some time for it to get killed due to the blocking os.system () call and due to the time.sleep () you have at the end of your Pinger.start_ping () method.The concurrent.futures module provides a high-level interface for asynchronously executing callables. The asynchronous execution can be performed with threads, using ThreadPoolExecutor, or separate processes, using ProcessPoolExecutor. Both implement the same interface, which is defined by the abstract Executor class.The process doesnt have to be multithreaded from Python but from shell. Put your shell script inside a function and call it appending a amperstand (&) to call it in another process. You can kill it finding the PID.

Finally, here are a few advantages and disadvantages of multithreading: Advantages: It doesn’t block the user. This is because threads are independent of each other. Better use of system resources is possible since threads execute tasks parallely. May 3, 2017 · Threading in python is used to run multiple threads (tasks, function calls) at the same time. Note that this does not mean that they are executed on different CPUs. Python threads will NOT make your program faster if it already uses 100 % CPU time. In that case, you probably want to look into parallel programming.

Python threading is great for creating a responsive GUI, or for handling multiple short web requests where I/O is the bottleneck more than the Python code. It is not suitable for parallelizing computationally intensive Python code, stick to the multiprocessing module for such tasks or delegate to a dedicated external library.Python’s Global Interpreter Lock (GIL) only allows one thread to be run at a time under the interpreter, which means you can’t enjoy the performance benefit of multithreading if the Python interpreter is required. This is what gives multiprocessing an upper hand over threading in Python.
