Depends on exactly what you are doing with numpy.f2py. The Python API
is (by logical necessity) more capable than the executable.

No, because the module knows nothing about where an executable might
be installed. There might be several executables, in fact.

It would be better to just execute [sys.executable, '-c', 'from
numpy.f2py.f2py2e import main;main()']
