I guess I'm confused if you want (e.g.) `python json.py` to do something but not `python -m json` to call the same file (a different way), given you're in the directory.
nick@lappy386:~/Code$ echo "{}" | python -m json.tool {} nick@lappy386:~/Code$ touch json.py nick@lappy386:~/Code$ echo "{}" | python -m json.tool .../bin/python: Error while finding module specification for 'json.tool' (ModuleNotFoundError: __path__ attribute not found on 'json' while trying to find 'json.tool') nick@lappy386:~/Code$ echo "{}" | python -I -m json.tool {}
Isolated mode effectively ignores the environment (variables and directory), so it will only use what's in that Python's site-packages (non-user, but could be a virtualenv)
If you want the local path to not be on `sys.path` for a *script-like* call, you could do `python -I myscript.py`, but `-m mypkg` is I think indistinguishable from trying to `import mypkg`, so it needs to be discoverable on `sys.path`...this feels like an A/B problem: what are you trying to do?

https://docs.python.org/3/using/cmdline.html#id2 -I Run Python in isolated mode. This also implies -E and -s. In isolated
mode
sys.path contains neither the script’s directory nor the user’s site-packages directory. All PYTHON* environment variables are ignored, too. Further restrictions may be imposed to prevent the user from

Oooh... Can you provide some examples on the use of -I?
I try to use along with -m (`python -I -m a.b`) and get this error: "python: Error while finding module specification for 'a.b' (ModuleNotFoundError: No module named 'a')".
On the other hand `python -m a.b -I` just passed -I as a script's CLI argument.
Of course, I get the expected results if run `python -I` on terminal. _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-leave@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/QTZRM5...
