Oo! Do you have the simplified Python connection already done?

I'm making blocks and a module for Python 3.2

can you put me in the credits for the mods name?

That's for the wiki. take this sentence out if you quote!

lawl its far from done.

- added konnect menu
- changed title
- added 6 new sensing blocks
- that's all really...

I already started, sorry. can you just post the code and blockspecs? I'm sorry for being such a hassle.
