For some reason, I have this repository watched for messages.

As the message states, Coral only works with Python 2, and you're running Python 3.

Out of curiosity, I did play around a bit with the code to see how difficult it would be to update it. The Python2→3 situation doesn't seem that bad. Generally:

• 2to3 gets a lot of the code to import.
• The cython extension just needs to have a more recent cython run on it, then it compiles.
• nosetests/nose no longer works with python ≥3.12, and replacing this is potentially a nuisance.
• biopython made a number of backwards-incompatible changes.
• there are probably other backward-incompatible library changes.

The quick results of my playing around are in https://github.com/cgevans/coral/tree/python3 . If someone wanted to spend some time updating this for Python 3, it probably wouldn't be that difficult.
