In any case, we dropped support for 2 so we can remove the u prefixes. It seems that the Unicode syntax in python 3 was dropped in python 3.0 and reintroduced on 3.3. We were all using 3.5 to test.

To get you going again quickly, You can either revert the commit that made python 3 the default and use python 2, or open the python files runtests.py testlib.py and testutil.py and do a global search and replace for u' and drop the u.

Yikes. I can’t run the testsuite on Linux (debian ? I think…). See below.

I installed python3 by saying

            apt-get install python3

And indeed

python3 --version

Python 3.2.3

This is bad. Can anyone help?
