I planned on using python to simulate different cipher to challenge myself,

and wanted to get NumPy and MatPlotLib modules imported to python.
Basically, I downloaded python 3.7.1 first, but when I realized it was not
compatible with TensorFlow (I wanted to make a machine learning algorithm
at a point in time), I uninstalled it to get python 3.6.1.
Windows easily allows multiple versions to be installed. The py
launcher lets you easily pick which to run (from a command console).
For 3.6, use the latest release, now 3.6.8, which has hundreds of fixes
since 3.6.1.
If you have multiple versions, you must install 3rd party modules for
each version you want to import them into.
Somehow, maybe I
misread a stack overflow post, but I deleted all my path files to python36
for whatever reason. I still have no idea why I did this. Then, I thought,
if I could uninstall python 3.6.1 and reinstall it pip would come back and
I could use python from the cmd. I uninstalled it and tried reinstalling
(with chocolatey this time) it for no avail. I tried searching for all the
correct environment variables to put them back in manually, but I cannot
seem to find most of them since python is still “not recognized as an
internal or external command, operable program or batch file.”
There is, or at least used to be, an option to add the python directly
to PATH. But using py instead python is needed anyway to select from
multiple versions.
In my cmd. I really want pip to work so I can download modules.
By default, the PSF Windows installer installs pip, using the ensurepip
module. If this did not happen, you can run it yourself. See
https://docs.python.org/3/library/ensurepip.html
The pydev recommended way to run pip on windows is
> py -x.y pip <pip options>
as this installs the package requested into the x.y site-packages
directory.
