Note: The following post was originally published over on Dzone. I changed the title because I already wrote several XML parsing articles and don’t want my readers to get this one confused with the others. One of the common tasks I am given in my day job is to take some data format input and […]

Occasionally I’ll see someone on the wxPython users group ask about how to make the wx.Notebook change pages (or tabs) programmatically. So I decided it was about time I figured it out. Here is some code that works for me: import random import wx ######################################################################## class TabPanel(wx.Panel): #———————————————————————- def __init__(self, parent, page): “””””” wx.Panel.__init__(self, parent=parent)

Virtual environments can be really handy for testing software. That’s true in programming circles too. Ian Bicking created the virtualenv project, which is a tool for creating isolated Python environments. You can use these environments to test out new versions of your software, new versions of packages you depend on or just as a sandbox

Pip Installs Python or pip is a tool for installing and managing Python packages, many of which are on the Python Package Index (PyPI). It is a replacement of easy_install. In this article, we’ll spend a little time trying out pip to see how it works and how it might help us in our Python

This week, I came across a fun Python project named psutil on Google Code. It says it works on Linux, Windows, OSX and FreeBSD. What it does is grab all the running processes and gives you information on them and also gives you the ability to terminate them. So I thought it would be fun

Today we’re going to take a look at the controversial easy_install method of installing Python modules and packages. We will also learn how to create our own *.egg files. You will need to go get the SetupTools package to follow along. This package doesn’t support Python 3.x so if you need that, see pip or

The other day on StackOverflow I saw someone who was struggling with the Wizard widget from wxPython. The wizard doesn’t allow much customization when it comes to its buttons, so I decided to see how hard it would be to just write my own Wizard. This code is pretty limited, but here’s my first beta

Today I learned that the pyPDF project is NOT dead, as I had originally thought. In fact, it’s been forked into PyPDF2 (note the slightly different spelling). There’s also a possibility that someone else has taken over the original pyPDF project and is actively working on it. You can follow all that over on reddit

Today we’ll be looking at a simple PDF generation library called pyfpdf, a port of FPDF which is a php library. This is not a replacement for Reportlab, but it does give you more than enough to create simple PDFs and may meet your needs. Let’s take a look and see what it can do!

Last time we learned how to create modules and packages. Today we’re going to take the package we created and use Python’s distutils to create a couple different ways to distribute our code. In this tutorial, we’ll be learning the following: How to create a setup.py file How to create a source distribution How to

Creating Python modules is something that most Python programmers do every day. Any time you save a new Python script, you have created a new module. You can import your module into other modules. A package is a collection of modules. The things you import into your scripts from the standard library are modules or

I’m always on the lookout for Python PDF libraries and I happened to stumble across pdfrw the other day. It looks like a replacement to pyPDF in that it can read and write PDFs, join PDFs and can use Reportlab for concatenation and watermarking, among other things. The project also appears slightly dead in that

My long time readers may remember me mentioning that I was trying to put my article code into a Mercurial repository on bitbucket. I haven’t been doing a very good job of that lately, but I did decide to release a whole bunch of wxPython example scripts on there. I use them a lot when

A couple years ago I wrote a rather flawed tutorial about SQLAlchemy. I decided it was about time for me to re-do that tutorial from scratch and hopefully do a better job of it this time around. Since I’m a music nut, we’ll be creating a simple database to store album information. A database isn’t
