The question is What is an environment variable 'and why should I change the value of the variable' path '?
Environment variables are a set of dynamic named values that can affect the way running processes will behave on a computer
You change this so you can run a python script in any directory, without the hassle of moving all python scripts into the directory C:\PythonXX (X being the version)
For proper operation of python on my SO, I create and / or modify any environment variable?
no, just the PATH env variable
I am creating my first scripts. I'm interested in creating a folder with the scripts created and can it call (run) from other scripts. Where should I put that folder?
You can put it anywhere as long as you changed the envrionmental variable. If not it will only run in the PythonXX directory. Which is why you would want to change it.
if you get lost. And if you are still lost after reading it, post why so we can update it to accommodate everyone.
