Most CPU manufacturers are creating multi-core CPUs now. Even cell phones come with multiple cores! Python threads can’t use those cores because of the Global Interpreter Lock. Starting in Python 2.6, the multiprocessing module was added which lets you take full advantage of all the cores on your machine. In this article, you will learn

The multiprocessing module was added to Python in version 2.6. It was originally defined in PEP 371 by Jesse Noller and Richard Oudkerk. The multiprocessing module allows you to spawn processes in much that same manner than you can spawn threads with the threading module. The idea here is that because you are now spawning

Descriptors were introduced to Python way back in version 2.2. They provide the developer with the ability to add managed attributes to objects. The methods needed to create a descriptor are __get__, __set__ and __delete__. If you define any of these methods, then you have created a descriptor. The idea behind the descriptor is to

Python provides the importlib package as part of its standard library of modules. Its purpose is to provide the implementation to Python’s import statement (and the __import__() function). In addition, importlib gives the programmer the ability to create their own custom objects (AKA an importer) that can be used in the import process. What about
