This article looks at the Qt library, with a focus on the PyQt bindings that let Python programmers access Qt functionality.
The Part 3 of the series continues the discussion by illustrating additional capabilities, like currying and other higher-order functions contained in the Xoltar Toolkit. Article includes code snipets.
This column continues the introduction to functional programming (FP) in Python. The introduction to different paradigms of program problem-solving demonstrates several intermediate and advanced FP concepts. Article includes code snipets.
Although users usually think of Python as a procedural and object-oriented language, it actually contains everything you need for a completely functional approach to programming. This article discusses general concepts of functional programming, and illustrates ways of implementing functional techniques in Python.
Along with several other popular scripting languages, Python is an excellent tool for scanning and manipulating textual data. This article summarizes Python's text processing facilities for the programmer new to Python. The article explains some general concepts of regular expressions and offers advice on when to use (or not use) regular expressions while processing text.

Python has a very extensive, well documented and portable module library that provides a large variety of useful functions. The Internet-related collection is particularly impressive, with modules to deal with everything from parsing and retrieving URL's to retrieving mail from POP servers and everything in between. Main topics include: Why should my next CGI project be in Python? Your First CGI program in Python, Getting some real work done, Defining a useful Display function, Putting the pieces together, and Simple Database Access.
Many parsing tools have been written for Python. This column discusses a high-level parsing language built on top of Python. SimpleParse provides an EBNF-style syntax on top of mxTextTools that can greatly clarify the expression of grammars.
Extending Python in C is easy once you see how it all works, and an extension of Python is equally easy to package up for Zope. The hard part is wading through the different documentation sets in search of the nuggets of information you need, and this article has collected them for you. Article includes code snipets.
Pippy is a port of (a subset of) Python to the PalmOS. With Pippy, Python programmers can create custom applications to run on Palm devices, as well as use Pippy as an interactive environment directly on the Palm. This article evaluates the strengths and limitations of Pippy as a means of implementing Palm applications.
