New submission from Géry <gery.o...@gmail.com>: Nicholas, I have noticed that `runpy.run_path` alters `sys.path` as expected for a file_path argument which is a valid `sys.path` entry (typically a directory or zip file). That is to say it adds the file_path argument to the beginning of `sys.path`, like `python <valid sys.path entry>`.
However, I have also noticed that `runpy.run_path` does not alter `sys.path` as expected for a file_path argument which is a Python source or bytecode file path. That is to say it does not add the *parent path* of the file_path argument to the beginning of `sys.path`, contrary to `python <source or bytecode file path>`. Likewise, I have also noticed that `runpy.run_module` (with the alter_sys argument set to `True` of course) does not alter `sys.path` as expected. That is to say it does not add the path of the *current directory* to the beginning of `sys.path`, contrary to `python -m <module>`. Only the first of the three previous `sys.path` manipulations is documented in https://docs.python.org/3/library/runpy.html though, so the `runpy` implementation is at least compliant with its specification. So is the mismatch between the manipulation of `sys.path` by `runpy` and by the Python command-line interface a specification bug or is it the intended behaviour? ---------- components: Library (Lib) messages: 377171 nosy: maggyero, ncoghlan priority: normal severity: normal status: open title: Mismatch between the manipulation of `sys.path` by `runpy` and by the Python command-line interface type: behavior versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41814> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
