--python python3.11 results in an error #1150
Description
Describe the bug
- The output of
--helpexplains thatpipx runsupports--python python3.11. - My testing shows that this results in an error
- I tested on 1.3.3 and the latest version from main
- A workaround is to use
--python 3.11 - Edit I tested with the
python-launcherpackage installed on Fedora 38
How to reproduce
Command to reproduce this bug:
pipx run --python python3.11 pycowsay moo
Error message:

Command to show pipx version:
pipx --version
Output:
1.3.3
Also tested with:
1.3.4.dev8+gb66335c
Expected behavior
Command to show help:
pipx run --help
Excerpt from help:
--python PYTHON Python to run with. Possible values can be the executable
name (python3.11), the version to pass to py launcher (3.11),
or the full path to the executable. Requires Python 3.8 or
above.
I therefore expect the two commands below to be equivalent:
pipx run --python python3.11 pycowsay moo
pipx run --python 3.11 pycowsay moo
They should both display a mooing cow:
