[docs] [issue15148] shutil.which() docstring could be clearer

Brian Curtin <brian@python.org> added the comment: I updated file to command in 973b4806f760. It needs to be command so it matches the implementation's argument name, and because it doesn't exactly take a file. Alexander, can you explain the part about finding a file on PYTHONPATH? I don't think this has anything to do with shutil.which, or at least I have no idea how it would. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue15148> _______________________________________
