"Python Cookbook (3rd edition) Chinese version" describes the Python application in various areas of the use of techniques and methods, its topics cover the data structure and algorithms, strings and text, numbers, dates and times, iterators and generators, files and I/O, data encoding and processing, functions, Classes and objects, metaprogramming, modules and packages, networking and web programming, concurrency, utility scripting and system management, testing, debugging and exceptions, C language extensions, and more.
This book covers many of the common problems in Python applications and presents a common solution. The book contains a lot of practical programming skills and sample code, and in the Python 3.3 environment tested, can be easily applied to the actual project. In addition, the Chinese version of Python Cookbook (3rd edition) also explains in detail how the solution works and why it works.
The Python Cookbook (3rd edition) Chinese version is ideal for Python programmers with a certain programming foundation to read the reference.
