Python is an agile, robust, and expressive programming language that continues to build momentum. It combines the power of compiled languages with the simplicity and rapid development of scripting languages. In Core Python Applications Programming, Third Edition, leading Python developer and corporate trainer Wesley Chun helps you take your Python knowledge to the next level.

This book has everything you need to become a versatile Python developer. You will be introduced to multiple areas of application development and gain knowledge that can be immediately applied to projects, and you will find code samples in both Python 2 and 3, including migration tips if that’s on your roadmap too. Some snippets will even run unmodified on 2.x or 3.x.

• Learn professional Python style, best practices, and good programming habits
• Build clients and servers using TCP, UDP, XML-RPC, and be exposed to higher-level libraries like SocketServer and Twisted
• Develop GUI applications using Tkinter and other available toolkits
• Improve application performance by writing extensions in C/C++, or enhance I/O-bound code with multithreading
• Discover SQL and relational databases, ORMs, and even non-relational (NonSQL) databases like MongoDB
• Learn the basics of Web programming, including Web clients and servers, plus CGI and WSGI
• Expose yourself to regular expressions and powerful text processing tools for creating and parsing CSV, JSON, and XML data
