I've been trying to expand my Python knowledge and recently came across Nick Parlante's 6-part learn Python series on Youtube. I've watched several of the videos, and I am impressed with Nick's teaching ability. Here are links to the 6-part series:
Day 1 part 1: Introduction and Strings: Watch on YouTube
Day 1 part 2: Lists, Sorting and Tuples: Watch on YouTube
Day 1 part 3: Dicts and Files: Watch on YouTube
Day 2 part 1: Regular Expressions: Watch on YouTube
Day 2 part 2: OS and Commands Watch on YouTube
Day 2 part 3: URLs, HTTP and Exceptions Watch on YouTube
If you are looking to learn Python this is a great place to start!
