XML is a fairly simple format. It uses plain Unicode text rather than binary encoding, and all the structures are declared with predictable-looking tags. Nonetheless, there are still enough rules in the XML grammar that a carefully debugged parser is needed to process XML documents -- and every parser imposes its own particular programming style. An alternative is to make XML even simpler. The open-source PYX format is a purely line-oriented format for representing XML documents that allows for much easier processing of XML document contents with common text tools like grep, sed, awk, wc, and the usual UNIX collection.
This article presents the xml_objectify module. It describes how to use xml_objectify and the advantages of using this "Pythonic" module for working with XML documents as objects.
As part of the ongoing quest to create a more seamless integration between XML and Python, this article presents the xml_pickle module. The author discusses the design goals and decisions that went into xml_pickle and provides a list of likely uses.
As the volume of information grows, effective means of locating specific information become ever more crucial. This column discusses the field of full-text indexing, with a focus on the author's public-domain indexer module.
This article introduces the idea of importing Python modules that manage many common and/or special tasks that you would otherwise have to write programming code for. IDLE is featured in this article because of some of its handy features, but you can follow the examples in other ways as well.
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.
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.
In this tutorial we will create a little application written in PyGTK and we will use Glade to create the graphical use interface (GUI). Another feature of this tutorial is that we will create a bar chart with Matplotlib.
This document is a syllabus for a first course in Python programming. This course contains an introduction to the Python language, instruction in the important and commonly used features of the language, and practical excercises in the use of those features.
This document is a syllabus for a second course in Python programming. This course contains discussions of several advanced topics that are of interest to Python programmers.
This is a tutorial to help the non-programmer learn the basics of using Python. When you are done with it, you will be ready to learn this new language, and have no problems figuring out where to find the information you need to go farther
People are always asking how to use Python in Web programming. As a general rule the only option to use Python in shared hosts is through CGI. This tutorial is just about how to use CGI with Python
wxPython is a toolkit for creating cross platform graphical user interfaces (GUI) for the programming language Python. wxGlade is a GUI designer for wxPython
The Qt toolkit is a widely-used cross-platform GUI toolkit, available for Windows, Linux, Mac OSX, and handheld platforms. QT has a well-structured, but flexible, object-oriented organization, clear documentation, and an intuitive API. This article looks at the Qt library, with a focus on the PyQt bindings that let Python programmers access Qt functionality.
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
