Among the many great talks
coming to PyOhio at the end of this month:
The IPython Notebook Revolution Catherine Devlin If you think of IPython as simply an enhanced version of the live Python prompt, you are in need of re-education. No matter what you do with Python, applying the (more...)
If any object has a _repr_html_
method, the IPython Notebook will use it to render HTML output. It's really easy to make a simple class that permits general dynamic HTML-rich output with Markdown. Markdown is a superset of HTML, so HTML in your output string will work, too.
Thanks to Mike Wilson, ipython-sql now supports bind variables!
In : name = 'Countess'
In : %sql select description from character where charname = :name

When I upgraded from Xubuntu 12.10 to 13.04 today, all my existing Python virtualenvs broke! Fortunately, they're just virtualenvs and easy to replace (that's kind of the point). But don't panic if you start seeing these.

Have you responded yet to PyOhio's Call For Proposals (due date: June 1)? You should. Here's why.
Why you should speak at PyOhio We need you. We have a great group of people who contribute talks, but we don't ever want that group to become a stagnant pool - we (more...)
For my newest ipython-sql trick, I needed to compare some queries run across different databases. How hard would it be to get side-by-side results into tidy IPython Notebook output?
Not hard at all, it turns out, if you're willing to violate basic principles of human decency.
That's an itty-bitty image, (more...)
Dayton folks - are you coming to the Dayton Linux User Group's Installfest tomorrow?
The main point of our Installfests is to get everyone together for mutual help setting up and configuring computers and programs. But we like to throw in some educational talks, too, and I volunteered to give (more...)
After getting %sql magic for IPython working, my next big goal was to figure out how to get those results into Pandas.
Er, OK, not such a big goal. Even with zero Pandas experience, it took about five minutes of skimming the first page of documentation to figure out:
On my morning commute today I realised that I am actually living in the future. I remember when I got involved in the PythonCard project 10 years ago one of the major questions on the mailing list was why we were building a GUI toolkit when the future was the web. It wasn’t true then but I think that it is now.
Why do I think we have moved now? It is in large part thanks to a book I have started reading called Python for Data Analysis. I have a copy of the book in ePub format and wanted (more...)
Ruby developers are a pretty spoilt bunch these days. The community has overall done a great job of rolling many of the advances in modern development practice into the tools and conventions we unconsciously put to work every day.
Now I wonder what life is like in the Python community?
Like many Rubyists, I've played around with Python and Jython on and off. But nothing serious. And although you could get into a pedantic syntax war, I suspect for the most part the Python and Ruby communities don't overlap simply because once you dive into one camp, the only real (more...)
The MySQL documentation section has always had this Topic Guides page containing links to the docs for the various MySQL Connectors -- the official database drivers for various languages and programming technologies. That is the most convenient way to get the information for each Connector in PDF form, rather than downloading the entire Ref Man PDF. For HTML, it was more of a shortcut, because
I’ve recently written some code to wrangle XML files. Part of the code validates a provided file against an XML Schema stored in a file. When I wrote this code I got tangled up in absolute and relative path manipulations trying to load the XML Schema file. Most of the Python file operations work relative to the current working directory and I needed to be able to load my XML Schema from a file relative to the application root directory. Regardless of where the code was executed from the schema file would always be up and across from the directory (more...)
