Python code analysis can be a heavy subject, but it can be very helpful in making your programs better. There are several Python code analyzers that you can use to check your code and see if they conform to standards. pylint is probably the most popular. It’s very configurable, customizable and pluggable too. It also […]

Today we’ll spend some time looking at three different ways to make Python submit a web form. In this case, we will be doing a web search with duckduckgo.com searching on the term “python” and saving the result as an HTML file. We will use Python’s included urllib modules and two 3rd party packages: requests

This week there were several fun things to read about in the Python ecosystem. You can read about a cool new Mercurial mirror of the Python repo, discover simple queues with redis and learn how to take an SQL statement and reverse engineer it into SQLAlchemy code. I’m not sure why you’d do that last

Downloading files from the internet is something that almost every programmer will have to do at some point. Python provides several ways to do just that in its standard library. Probably the most popular way to download a file is over HTTP using the urllib or urllib2 module. Python also comes with ftplib for FTP

A couple years ago I started a series of articles on XML parsing. I covered lxml’s etree and Python’s included minidom XML parsing library. For whatever reason I didn’t notice lxml’s objectify sub-package, but I saw it recently and decided I should check it out. To my mind, the objectify module seems to be even

I was recently contacted about whether or not there were any wxPython applications out here that could present a SQLite database. As I understood it, they wanted to be able to introspect the database and view the tables, probably using the wx.grid.Grid widget. I find the Grid widget to be very powerful and also rather

It may have been a better idea to have called this this article “How to Convert Floats to Words”, but since I’m talking about currency, I thought using Decimal was more accurate. Anyway, a couple years ago, I wrote about how to convert numbers to Python. The main reason I’m revisiting this topic is because

It’s the first Friday of June and I’ve read a bunch of new articles this week. From the Vern’s rant about getting Python jobs to a review of the web2py cookbook, there’s lots of fun things going on in Python land. Here are just a few other articles I thought were interesting: Batchelder talks about

Last week, I was reading Brett Cannon’s blog where he talks about function signatures and decorating the main function. I didn’t follow everything he talked about, but I thought the concept was really interesting. The following code is an example based on a recipe that Mr. Cannon mentioned. I think it illustrates what he’s talking

Everyone who uses computers regularly knows that they can copy and paste text. What they might not know is that when you copy something, it goes into a location known as the “clipboard”. Most programs provide access to a clipboard of some sort, whether it be just within the program itself or to the system

I haven’t done a weekly round-up of Python links because no one seemed to really care when I was doing those. However I thought I’d give it one more try and see if there was any interest this time around. This past week, I finished reading my first web2py cookbook. I’m told there’s another book

I have read about web2py on several occasions, but never used it myself. Then a few weeks ago, a representative from Packt Publishing contacted me about reviewing their new cookbook about web2py. It’s written by seven authors, namely: Richard Gordon, Pablo Martin Mulone, Mariano Reingart, Bruno Cezar Rocha, Massimo Di Pierro, Michele Comitini and Jonathan

Robin Dunn, creator and mastermind behind wxPython, announced today on his blog and the wxPython-dev mailing list that he had gotten wxPython 2.9 (Phoenix) to build successfully for Python 3.2 on Mac. In fact, he posted a Quicktime video that shows the build and the tests running in Python 3! According to wxPython-dev, once they

I’m a little excited today as my first patch (and first ticket even!) has been accepted. And it really didn’t take very long either. Less than 24 hours after I had submitted my first patch, I got my contribution added. I did have to submit to more variations of the patch though as my first

As I mentioned in my last article, I figured I’d try to find something that I could patch in Python and submit it. While writing the other article, I stumbled on a minor error in the Python devguide in the Windows section. While it’s nowhere near as cool to patch a piece of documentation as
