Subject: python 3.9.12 and python 3.10
I installed 3.9 and am able to enter simple code which runs. If I type an
error I can highlight it but cannot copy or delete it.
I looked for help & found 3.10 and installed it but when I selected the
python icon 3.9 appeared with my old errors. I uninstalled 3.10 as 3.9 did
not appear in control panel.
