I do a lot of PDF report creation with Python using Reportlab. Occasionally I’ll throw PyPDF in as well. So I’m always on the lookout for other mature Python PDF tools. PDFDocument isn’t exactly mature, but it’s kind of interesting. The PDFDocument project is actually a wrapper for Reportlab. You can get it on github.

The other day, I wrote an updated version of my wxPython pubsub article for wxPython 2.9 and realized I had never gotten around to trying PyDispatcher to see how it differed from pubsub. I’m still not sure how it differs internally, but I thought it would be fun to “port” the pubsub code from the

Every now and then, I see someone wondering how to create a progress bar and update it. So I decided to whip up an example application that updates a progress bar (technically a wx.Gauge widget) from a thread. In this tutorial, we will create a frame with a button. When the button is pushed, it
