Nice video! Very useful for newbies like myself.

Great video, thanks! IPython is a must-have tool :)

Simple, but incredibly useful! Filled in a trick the manual must have omitted as "obvious".

Very good!

Thanks, good intro to debugging on ipython

11. anonymous Wed, 26 Aug 2009 09:37

Thanks - concise and informative demo.

10. anonymous Wed, 05 Aug 2009 10:45

Nice, short, easy to understand. Even could be a bit quicker.

Basic but good. Thanks

Hi Anon, thanks for the tip :-) I might try to integrate this into one of our Learning Python videos in the future.

The breakpoint system is called by using the IPython run command. For example "run -d" would launch within the pdb and stop at line 1, allowing to set further breakpoints, etc. Hope this helps you create a breakpoint tutorial!

Hi anon. Yes, there are definitely usability-improvements over the standard pdb, I use IPython all the time.

Re. breakpoints - actually I don't use them...I'd love to have someone show me what they can do. We'd really appreciate more videos showing people how to use IPython, there are so many cool things inside the package.

Interesting demo, looks like some improvements over standard pdb. Would have been nice to see a breakpoint demo too. - Alan G.

Hi Vincent, as mentioned I did put a really simple WinPDB screencast online with SPE videos:

but it is rather old (a year old, I think). We'd certainly welcome some new videos on WinPDB!


Great screencast. Unfortunately, I was unable to use pdb, which Ipython calls for debugging, due to an error I could not diagnose, so instead of Ipython and pdb I ended up using Winpdb, which is graphic and says it is faster than pdb, though I have no basis for comparison. If no one else does it first, and the lead developer doesn't object, when I get some time I may do a screencast on Winpdb.

Good information. Thanks for the info.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for Ian
