Today we’ll be looking at how to acquire data from the popular movie site, Rotten Tomatoes. To follow along, you’ll want to sign up for an API key here. When you get your key, make a note of your usage limit, if there is one. You don’t want to do too many calls to their […]

Today we will be looking at how to get the selected cells from a wxPython grid object. Most of the time, getting the section is easy, but when the user selects more then one cell, getting the selection becomes more complicated. We will need to create some sample code to show how all this fits

We all write bad code from time to time. I tend to do it deliberately when I’m experimenting in the interpreter or the debugger. I can’t say why I do it exactly except that it’s fun to see what I can fit in one line of code. Anyway, this week I needed to parse a

The wxPython GUI toolkit comes with lots of widgets. We will be covering some widgets that are somewhat harder to get ones mind wrapped around. In this case, we will be talking about splitter windows. WxPython includes three types of splitter windows: wx.SplitterWindow fourwaysplitter which you can find in wx.lib.agw MultiSplitterWindow which you can find

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

NOTE: This article is for wxPython 2.9-3.0. If you are using wxPython 4, you should go to my newer article Several years ago, I wrote a tutorial about wxPython 2.8 and its built-in pubsub module which you can read here. Back then, a new API for pubsub was added in wxPython 2.8.11.0 that could be

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

This week I was trying to figure out how to make Reportlab do something I had never attempted before. Namely, I wanted to create about a half page’s worth of static text positioned exactly and then have a table of line items that could potentially fill the rest of the page and continue for N

Today I was reading the wxPython Google group / mailing list and there was someone asking about how to make Python’s logging module write its output to file and to a TextCtrl. It turns out that you need to create a custom logging handler to do it. At first, I tried just using a normal
