What can you offer in exchange? Tutoring for another language? Money? Ferrero Rocher chocolates?
Also do you have already a project in mind you’d like to build in Python? I find it much easier to learn if you’re building a real thing rather than doing meaningless exercises.
Not specifically what you're looking for, but #python in the freenode IRC network (as well as #programming and #yourlanguagehere) has been an invaluable learning resource, just to throw questions at and learn from the experience of others. I've also helped others on these channels, which broadens my own understanding while 'giving back'.
Not necessarily the same as a dedicated tutor, but it was helpful for me
There are several good Python books to start with depending on what you're trying to build. Many of them are published by O'Reilly. Have you considered going this route?
