Yes, I've been messing around with PATH and bouncing between Python 2
and 3. Anyway, it sounds like your version of Python has the exact
same issue. Two questions:

Is it possible you didn't recompile python.elc after applying the patch?

How does the test run at all if you don't have Python on PATH?

python-tests.el has:

    (defvar python-tests-shell-interpreter "python")
    ...
    (ert-deftest python-shell-calculate-command-1 ()
      "Check the command to execute is calculated correctly.
    Using `python-shell-interpreter' and
    `python-shell-interpreter-args'."
      (skip-unless (executable-find python-tests-shell-interpreter))
