The course is where the computer searches for Python if you sort it in your console/terminal/cmd/whatever you call it.
I am not that comfortable with Windows, since I have not used it , but it functions exactly the exact same manner. Essentially, path factor is a list of programs with apps in them.
On linux It May seem like usr/bin:/usr/local/bin:/usr/local/share/bin
All these are several directories which linux will appear in if I ask it to conduct an app for me. If I place python in /usr/local/share/bin afterward it will initially appear in /usr/bin, it is not there then it seems in /usr/local/bin, and it is not there so it seems in /usr/local/share/bin then finally finds it, and runs that program.
Should you unchecked that box, then opened up your terminal and then clicked’python’ then nothing could occur because Windows appeared through your route, assessed all those directories to find out if there was something known as’python’ in there, then there was not because it never got added to route, and comes back with nothing.
