An Introduction To Python

Although this is written as a textbook, it's much more of a guide (with examples and tasks) than a 'learn Python in xx days' type book. The advantage is that it's a lot lighter and (IMO) more accessible.

There are 1 or 2 typos at the minute, but the book is an ongoing work in progress that is very usable. I've been using it with my students for the last 2 years with (what I feel is) good success.

Update: Many thanks to Clarke Rice for adding a fork for Python 2.x and for correcting several typos.
