[Tutor] Python3 install windows 10

[Paul Simon]

I have been having trouble installing python 3.9.  I already have 2.7 
installed and running.  Python 2.7 is installed in a directory under c:\ 
but 3.9 is installed in an odd location under AppData?  Aside from 
having a unicode issue my script cannot find downloaded modules like 
seaborn and matplotlib.  They have been imported with pip3 into python 3.9.

Do I have to make a change to a path somewhere?  Some instructions?

Where can I find info on adapting text from python 2 to unicode python3?

Thanks,
Paul Simon
