I feel the exact same with the aforementioned frameworks. I too am learning Python and decided to learn it whilst hacking away with web.py. When I found myself building yet another MVC framework with web.py as its core. I moved on to Pylons as it presents a nice middle ground between web.py and Django. Its a framework with a bit more bent on web.py's spartanism. So far its been a nice journey and loving the language more and more.
