When I met one of SimPy's founder Klaus Miller, I learned about the bag from him. Dr. Miller has read several lovely Python columns that suggest techniques for using Python 2.2+ generators to implement semi-collaborative routines and "lightweight" threading. In particular (which I am pleased with), he found these techniques useful when implementing Simula-67 style simulations in
Python System Operations Common Library1. Psutil is a cross-platform library (http://code.google.com/p/psutil/)It is able to achieve the process and system utilization (memory, CPU, disk, network, etc.) of system running, which is mainly used for system monitoring, analysis and management of system resources and processes.2, IPy (http://github.com/haypo/

In the process of game development, it is often necessary to deal with time-related processing. And Python built a lot of time processing library, Datetime/date/time/calendar/timedelta, and so on, the details are slightly confusing. Very many things are not convenient direct.Consider the following scenarios:

Python implements multithreading primarily through the threading package in the standard library. In today's network era, each server receives a large number of requests. The server can handle these requests in a multi-threaded manner to improve the read and write efficiency of the network ports.
Two-dimensional code for short QR code (quick Response Code), scientific name for the fast Response matrix code, is a two-dimensional barcode, by the Japanese Denso Wave Company in 1994 invented. Now with the popularity of smartphones, has been widely used in ordinary life, such as commodity information inquiries, social interaction friends, network address access and so on.
