Threads are the smallest program units that an operating system can execute. Programming with threads allows that several lightweight processes can run simultaneously inside the same program.

In this intermediate-level tutorial, you'll learn how to use threading in your Python programs. You'll see how to create threads, how to coordinate and synchronize them, and how to handle common problems that arise in threading.
Python Threads: a Tutorial. Norman Matloff University of California, Davis. My tutorial on Python threads is now a (more or less independent) chapter in my open-source textbook on parallel programming, at http://heather.cs.ucdavis.edu/ ̃matloff/158/PLN/ParProcBook. pdf. 1.
Use the Python threading module to create a multi-threaded application. Use the Thread(function, args) to create a new thread. Call the start() method of the Thread class to start the thread. Call the join() method of the Thread class to wait for the thread to complete in the main thread.
The use of threads is aimed at checking many ports in parallel, one per thread. The program has a self-imposed limit on the number of threads. If main() is ready to start checking another port but we are at the thread limit, the code in main() waits for the number of threads to drop below the limit.
30 gru 2023 · This section provides an overview of the basics of threading in Python, focusing on thread creation, starting, and the thread lifecycle. In the next sections, we’ll explore advanced concepts, synchronization, and best practices for effective threading in Python.
