This patch is not good:

  - It skips the test on all platforms that don't have 'python' in $PATH.
    (Nowadays more platforms have 'python3'. The old name 'python' is not
    present on all platforms that have 'python3'.)

  - On FreeBSD 14.0, in an empty directory:
    $ python3.9 -c 'import os; os.listdir(".")'
    succeeds (exit code 0). In detail:
    $ python3.9
    >>> import os
    >>> os.listdir(".")
    []
    Conclusion: The python test does *not* actually test what you meant
    to test.
