About a year ago, I created a short series of videos that explain some of the basics of working with Python in Modo. The videos ended up being much more broad, and don't deal directly with Modo. The hope is to expand the series and show how to create some Modo specific tools and utilities, and eventually even PySide UIs. If you have any comments or requests, please don't hesitate to let me know! Below is a link to the collection and the first video of the series, which is the introduction.
