This part of the book explores Python's role as a language for programming Internet-based applications, and its library tools that support this role. Along the way, system and GUI tools presented earlier in the book are put to use as well. Because this is a popular Python domain, chapters here cover all fronts:
Chapter 10. This chapter introduces Internet concepts, presents Python low-level network communication tools such as sockets and select calls, and illustrates common client/server programming techniques in Python.
Chapter 11. This chapter shows you how your scripts can use Python to access common client-side network protocols such as FTP, email, HTTP, and more.
Chapter 12. This chapter covers the basics of Python server-side CGI scripts -- a kind of program used to implement interactive web sites.
Chapter 13. This chapter demonstrates Python web site implementation techniques such as security, by presenting a web-based email system.
Chapter 14. This chapter presents additional web site techniques including persistent data on the server, by presenting a bug report system.
Chapter 15. This chapter gives an overview of Python Internet systems and tools, such as JPython, Active Scripting, Zope, and HTMLgen.
