Записки программиста, обо всем и ни о чем. Но, наверное, больше профессионального.

Multithreaded Python Tutorial

Меньше чем 300 строк кода содержит программа на Python, демонстрирующая многопоточную реализацию игры Nibbles.
К программе прилагается статья, подробно рассказывающая что, зачем и как — про многопоточность в Python.

Okay, let’s write a Python program that demonstrates how to use threads and locks. This program is based off of my “Snake” clone in Chapter 6 of my Making Games with Python & Pygame book. Except instead of a worm running around eating apples, we’ll just have the worm running around the screen. And instead of just one worm, we will have multiple worms. Each worm will be controlled by a separate thread. The shared variable will have the data structure that represents which places on the screen (called “cells” in this program) are occupied by a worm. A worm cannot move forward to occupy a cell if another worm is already there. We will use locks to ensure that the worms don’t occupy the same cell as another worm.


Всем, кто интересуется параллельностью и многопоточностью в Python — читать немедленно.

И не забывайте про GIL, зарубающий полезность многопоточных Python программ на многоядерных процессорах.
