Last time, we looked at one of Python’s built-in XML parsers. In this article, we will look at the fun third-party package, lxml from codespeak. It uses the ElementTree API, among other things. The lxml package has XPath and XSLT support, includes an API for SAX and a C-level API for compatibility with C/Pyrex modules. […]

If you’re a long time reader, you may remember that I started programming Python in 2006. Within a year or so, my employer decided to move away from Microsoft Exchange to the open source Zimbra client. Zimbra is an alright client, but it was missing a good way to alert the user to the fact

Packt Publishing gave me an ebook copy of their brand new book, MySQL for Python by Albert Lukaszewski. I’ll be working on reading through that this month and will hopefully have a review for all of you to read before December. They also gave me this link to a free chapter. Feel free to read

If you’re new to wxPython but not new to XML, you might find this article useful to you. Why? Because wxPython supports XRC, an XML file format that describes the GUI in XML, duh. In fact, wxPython’s Documentation & Demos package includes an editor just for creating and manipulating these files that is called, XRCed.

A couple of months ago at work, we received a report that a file was locked. The dialog that appeared showed the initials of a user who wasn’t even working for us any more. Thus we discovered an annoying bug that can crop up with Office. Basically, a user is asked by Word or Excel

One of my first self-imposed projects at my job was to recreate a certain annoying application that was a Frankenstein monster: a Microsoft Access file with a VBA GUI. For the most part, the application didn’t even have a database. Anyway, part of the application allowed the user to type in an amount for a

Earlier this year, I was tasked with creating an application that would download information from our organization’s website using Python. The tricky part was that it would be encrypted, gzipped and the payload would be JSON. Could Python do all that? Well, that’s what I wanted to find out. Now it’s time for you to

I’ve been working on an article about the various Python projects that took part in the 2010 Google Summer of Code for over a month. There are a lot of projects and people to contact and I would say of the ones that I did contact, only 50-60% responded back. So I’m going to go

The wxPython project is one of the most popular and easy to use Python GUI toolkit. It wraps the popular C++ wxWidgets project using SWIG. It is also the only cross-platform toolkit that I am aware of that uses the native widgets on each platform wherever possible (for better or for worse). Some like to
Whether you’re new to Python, been using it for a few years or you’re an expert, knowing how to use Python’s introspection capabilities can help your understanding of your code and that new package you just downloaded with the crappy documentation. Introspection is a fancy word that means to observe oneself and ponder one’s thoughts,

The other day, I was tasked with finding a way to get a list of all running processes on a Windows XP virtual machine. I was also supposed to include information about how much CPU and memory each process used. Fortunately, this didn’t have to be a remote script, but one that could be run

Some people learn through doing it, others are better with visual stimuli. At least, that’s what we’re told. So in the spirit of what we’ve been taught, we’re going to take a look at the visual half of the equation and see how we can make graphs with wxPython. You may not know this, but

This week, I finished editing another book for Packt Publishing. The book’s name is Python Graphics Cookbook by Mike Ohlson de Fine (I think). You may wonder why I don’t know if de Fine is the author. Well, Packt thinks that its Technical Editors shouldn’t know that information. In fact, Packt is so cagey (and

Back in March of this year, I wrote a simple tutorial on Reportlab, a handy 3rd party Python package that allows the developer to create PDFs programmatically. Recently, I received a request to cover how to do tables in Reportlab. Since my Reportlab article is so popular, I figured it was probably worth the trouble
