In the first part of this series, we went over what some might call the “SQL Expression” method of using SqlAlchemy to interact with your database. The theory behind this is that we should learn the less abstract way of doing things before we get to the higher level (and more abstract) methods. This is […]

A long time ago (circa 2007 if Google serves me right), there was a Python programmer named Robin Munn who wrote a really nice tutorial on SqlAlchemy. It was originally based on the 0.1 release, but updated for the newer 0.2. Then, Mr. Munn just disappeared and the tutorial was never updated. I having been kicking around the idea of releasing my own version of this tutorial for quite some time and finally decided to just do it. I hope you will find this article helpful as I found the original to be.

Another script I had to come up with for my employer dealt with getting various bits and pieces of information about each of our user’s physical machines. We wanted to keep track of the CPU speed, hard drive sizes and the amount of RAM they had (among other things) so we would know when it

A few days ago, I wrote an article about using ConfigObj with wxPython. The first question I was asked about the article regarded using a configuration file to generate the dialog. I thought this was an interesting idea, so I took a stab at implementing that functionality. Personally I think it would be probably be

Python comes with a handy module called ConfigParser. It’s good for creating and reading configuration files (aka INI files). However, Michael Foord (author of IronPython in Action) and Nicola Larosa decided to write their own configuration module called ConfigObj. In many ways, it is an improvement over the standard library’s module. When I first looked

During the summer, I stumbled upon an article on Ars Technica about using PyGTK to create a URL shortener. I thought that was pretty interesting, but I don’t use PyGTK. So at that point, I decided to write my own using wxPython and use the article’s code to do the shortening. I hacked together something

Last week, I embarked on an adventure into the world of web application programming. Since my work place uses Python as much as possible and my boss likes TurboGears, I chose it for this endeavor. I have worked through various TurboGears tutorials and thought it looked pretty cool. However, it doesn’t take long to discover

I received Ayman Hourieh’s Django 1.0 Web Site Development from Packt Publishers a few weeks ago for review. I had worked with Django before when I went through another book on Python web frameworks as well as one of their official tutorials. I had my doubts about this book because it was only 257 pages

Steve Holden gave a talk on where Python is at Friday afternoon. For those not in the know, Holden is the current chairman of the Python Software Foundation (PSF). His first topic was about the PSF and how few member it had as well as how they were planning to add additional members at this

New programmers start using Python and wxPython each week. So it follows that every few months, I see people asking how to redirect stdout to a wx.TextCtrl on comp.lang.python or the wxPython mailing list. Since this is such a common question, I thought I would write an article about it. Regular readers will know that

I recently started a Python Users Group for Iowa as there didn’t seem to be one and I thought it would be fun. We had our first meeting last Wednesday, the 24th of September, 2008. We had eight people there, including myself. Of that group, only half knew how to program in Python. Thus, we

As planned, I copied some of my tutorials to the official wxPython wiki. Currently I only have the sizer tutorials over there. I am working on a series that will show how to build a simple application from the ground up. Hopefully I can take the bits and pieces of it and make it easy

In this tutorial, I will take my code from the GridSizer tutorial I wrote the other day and heavily modify it to display oddly shaped widgets in a GridBagSizer. The GridBagSizer is the most complex of the sizers. It subclasses the FlexGridSizer, so you can use all of it’s parent’s methods as well as those

One of the first scripts I had to help translate from Kixtart to Python was our map drives script. In it, we would map drives based on either which group the user was in and/or what a custom registry entry said. Here is a partial example of each of these categories in Kixtart: IF READVALUE(“HKEY_LOCAL_MACHINE\SOFTWARE\MyOrg”,
