It could just be a mismatch of expectations. With python-shell-interpreter set to "python2", tab-completion in the Python interactive shell works but in a diminished capacity. For example, 'pri<TAB>' completes to 'print' but 'math.sq<TAB>' does not complete to 'math.sqrt(' as it does in Python 3.

But it does fix a different problem: it tests python-mode with Python 3, which is more important.

We can probably agree that absent explicit information about what version the user wants tested, we should test python-mode with Python 3 on macOS and other platforms.

If you think it is important we can also test it with Python 2 if available. Rejigging the tests to run for multiple Python versions is certainly possible but would be some work.

Meanwhile I'm just going to make the tests use the same logic as python.el for selecting the binary to use, as there does not seem to be a reason why this would make anything worse.
