First of all, cocotb is the best thing since sliced bread. :)

Anyway, it is listed in the README that Python2.6+ is supported. But it does not work for python3k. After modifying the makefile to make it build (pull request attached), it is clear that there have been some changes to the python C api which makes the current cocotb codebase incompatible. I used all of the latest 3.4.0 dev packages available on Ubuntu 14.04.1.

Is support for python3 planned? I am considering giving it a go myself, though I'm not sure my skills are up to the task.

Hi Jeremy,

Thanks for this contribution and your supportive comments - it's always nice to hear that Cocotb is useful to other people.

Python 3 is something we would like to support, sadly to date it's simply something that has been buried in the eternally growing list of things to do. The same goes for ensuring pypy compatibility, which probably works but we may have introduced regressions.

We can set up a branch and enable Python3 and Pypy on travis and gradually fix up any issues. At least the amount of code that actually uses the C-API for Python is quite minimal.
