Below are the screencasts from the Python Course, organised and run by the Genome Discovery Unit. Each day is organised into 3 ~50 minute blocks. Download the videos to your computer. If you have trouble playing them, use the VLC player.
Please note that due to an operator error, the following two screencasts do not have an audio track I have put in links to equivalent content from my undergraduate lectures, ie lectures covering the same programming concepts. In the undergrad lectures I do not use the IPython notebook but the more conventional approach of editing a text file and running it in the terminal app.
See lecture 2.
See lectures 3,4,5.
