Last week, Matt Harrison sent me a copy of his latest Python eBook entitled Treading on Python Vol 2: Intermediate Python. I was intrigued since I rarely get to read Intermediate level Python books. In fact, I would say that some of the stuff that the author talks about goes into the advanced level. Anyway, […]

The Reportlab library is a great way to generate PDFs in Python. Recently, I noticed that it has the ability to do barcodes. I had heard about it being able to generate QR codes, but I hadn’t really dug under the covers to see what else it could do. In this tutorial, we’ll take a

This week, I needed to figure out how to attach an event handler that would fire when I double-clicked an item (i.e. row) in an ObjectListView widget that was in LC_REPORT mode. For some reason, there isn’t an obvious mouse event for that. There is an EVT_LIST_ITEM_RIGHT_CLICK and an EVT_LIST_ITEM_MIDDLE_CLICK, but nothing for LEFT clicks

This week I spent some time learning how to add check boxes to the ObjectListView widget in wxPython. If you don’t know, ObjectListView is a 3rd party wrapper for the wx.ListCtrl widget that makes using the ListCtrl much easier. You can read all about it in this older article from the archives. I had a

Last week I was contacted about a cool sounding book project on Kickstarter: Real Python for Web Development, featuring web2py by Michael Herman. I have to admit that I’m not familiar with Mr. Herman or the person who originally contacted me about the book, but since I enjoy reading Python books and this one sounded

A few days ago, InformationWeek announced that DARPA was funding the project to the tune of $3 million dollars to get some big data libraries written for Python. There will be two new projects, Blaze and Bokeh. Blaze will be an

The other day, I was trying to figure out if there was an easy way to grab a class’s defined attributes (AKA “instance variables”). The reason was that we were using the attributes we created to match up with the fields in a file we parse. So basically we read a file line-by-line and each

If you do much system administration, then you know that sometimes you have to write scripts that can move files between servers. I’m not really a system administrator by trade, but I did have to do this sort of thing in some of my programs anyway. Python has several 3rd party packages that provide this

Python provides robust exception handing baked right into the language. Exception handing is something every programmer will need to learn. It allows the programmer to continue their program or gracefully terminate the application after an exception has occurred. Python uses a try/except/finally convention. We’ll spend some time learning about standard exceptions, how to create a
