Hi Barry,
My sympathies, sometimes the learning curve can be a bit harsh.
Especially since tech tutorials often suffer from what I call the
“…and now you have muffins!” problem. It goes like this.
If cooks wrote recipes like developers write tutorials, they would go
like this:
"Today we are going to make muffins. Muffins are made from flour. Flour
is made from wheat, which is a grain from the genus Triticum. Wheat was
first domesticated in the Fertile Crescent around eleven and a half
thousand years ago. You can purchase flour from your local supermarket
or grocery store, by exchanging money for goods and services.
"Preheat your oven to 200°C (400°F) while you prepare the muffin batter.
The oven is a big metal box with a glass window, usually found in your
kitchen. It can operate by electricity or gas. In a large mixing bowl,
sift together the flour, baking powder and sugar. Add one cup of cow’s
milk. Goat’s milk is an acceptible substitute if you don’t have a cow.
Add a quarter of a cup of oil.
"Stir all the ingredients together and place them in a muffin tin. Put
the muffin tin in the oven.
“And now you have muffins!”
So let’s start with the basics: do you have Python installed, and if so,
do you have it more than once?
I’m not a Windows user, so I don’t have much experience in Windows, but
you should be able to find Python under the Start menu. I presume that
if it is installed more than once, it will be listed multiple times.
I’m afraid I can’t see your attached screen shot, all I get is this:

which isn’t very helpful
Can you use the Windows’ Find command to search for a file name called
“python.exe”? That should list any Python interpreters you have
installed, and will tell you if it is installed more than once or not.
If there is more than one, you should be able to find an uninstaller for
each of them. Run the uninstaller until there’s only one left. (I’m
afraid I can’t be more specific than that, I’m not a Windows guy.)
Then we can check whether Python will run. From the start menu, type
“Python” and hit enter. That should launch a console window and start up
the Python interpreter. You should get something like this:
Python 3.9.0 (default, Oct 24 2020, 11:55:24)
[GCC 8.3.1 20190223 (Red Hat 8.3.1-2)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
except it won’t say Linux of course.
Enter quit()
at the prompt >>>
to exit. If you can get past that
stage, you have the Python interpreter successfully installed and we
can move on to the next step.
