there was a typing mistake in the code of the previous variant.
The new version should be right (I hope)

You should see something like

$ /usr/sbin/alternatives --list
2to3                    auto    /usr/bin/2to3-3.9
automake-doc            auto    /usr/share/info/automake1.9.info.gz
gnuplot                 auto    /usr/bin/gnuplot-X11.exe
pip3                    auto    /usr/bin/pip3.9
pydoc3                  auto    /usr/bin/pydoc3.9
python                  auto    /usr/bin/python3.9
python3                 auto    /usr/bin/python3.9
python3-config          auto    /usr/bin/python3.9-config
sphinx-apidoc           auto    /usr/bin/sphinx-apidoc-3.9
sphinx-autogen          auto    /usr/bin/sphinx-autogen-3.9
sphinx-build            auto    /usr/bin/sphinx-build-3.9
sphinx-quickstart       auto    /usr/bin/sphinx-quickstart-3.9

with more variant if other python's are installed

$ /usr/sbin/alternatives --display pip3
pip3 - status is auto.
 link currently points to /usr/bin/pip3.9
/usr/bin/pip3.9 - priority 39
Current `best' version is /usr/bin/pip3.9.

Regards
Marco
