Beginner Python Practice?
You could also try CheckIO which is kind of a quest where you have to post solutions in Python 2.7 or 3.3 to move up in the game. Fun and has quite a big community for questions and support.
From their Main Wiki Page:
Welcome to CheckIO – a service that has united all levels of Python developers – from beginners up to the real experts!
Here you can learn Python coding, try yourself in solving various kinds of problems and share your ideas with others. Moreover, you can consider original solutions of other users, exchange opinions and find new friends.
If you are just starting with Python – CheckIO is a great chance for you to learn the basics and get a rich practice in solving different tasks. If you’re an experienced coder, here you’ll find an exciting opportunity to perfect your skills and learn new alternative logics from others. On CheckIO you can not only resolve the existing tasks, but also provide your own ones and even get points for them. Enjoy the possibility of playing logical games, participating in exciting competitions and share your success with friends in CheckIO.org!
Try Project Euler:
Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.
The problem is:
Add all the natural numbers below 1000 that are multiples of 3 or 5.
This question will probably introduce you to Python for-loops and the range() builtin function in the least. It might lead you to discover list comprehensions, or generator expressions and the sum() builtin function.
UPDATE (Jan 2020): There are many great online places to get beginner practice at Python, some which are highly engaging and/or otherwise interactive. These sites are generally more practical than the Python Challenge (http://pythonchallenge.com), which you can tackle later. (After years of experience, you can try the Python "wat" quiz). For now, it's most important to learn, practice, and have fun. Welcome to Python!

ps. BTW (by the way), your experience puts you right in the heart of the target audience of my Python book, Core Python Programming. That audience is those who know how to code in another high-level language but want to learn Python as quickly but as in-depth as possible. Reviews, philosophy, and other info at http://corepython.com
pps. The following resources were previously on the list but are no longer available.
