I cannot use Python 3.8 on my PC with installed Python 3.7.
Is it possible to update the existing Python 3.7 without reinstalling
Python 3.8.
Conflicts problems.
Thankyou

If the question is about updating Python 3.7 'in place' (and not
upsetting any applications or systems programs which use Python), then
"yes, this is possible": you may be able to update r3.7.0 to r3.7.4, for
example (only the last digit changes). I see few compelling reasons to
do-so, but YMMV (you have your own reasons).
The reason to update 3.7 or any x.y is to get the bugfixes, which
eventually number in the hundreds.
If the question is a desire to run both Python 3.7 AND Python 3.8 on the
same machine, then the PSL's (Python Standard Library) answer is "venv".
On Windows, the answer is to install 3.7 and 3.8 into separate
directories and use the py launcher, installed by the Windows python
installer, to select which to run.
