I am a total beginner to all of this so apologies if this seems obvious or simple:

A couple of years ago I played around with learning python and installed anaconda. I didn’t have the time to learn at that point so I ended up uninstalling and deleting anaconda, python, etc from my laptop.

I am now ready t start learning python, so today I installed the latest version through python.org and also jupyter notebook.
All seems to have intalled as expected.

However, when I go to command prompt and try to open jupyter notebook I receive the following error:

C:Usersmarck>jupyter-notebook
Fatal error in launcher: Unable to create process using ‘”C:Program FilesPython311python.exe” “C:UsersmarckAppDataRoamingPythonPython311Scriptsjupyter-notebook.exe” ‘: The system cannot find the file specified.

From my basic understanding it seems to be refering to the old version of python I had previously installed (but have since deleted). I have follwed these paths above and can see there are still folders and files present.

Any ideas on how to completely wipe all historic files and start a fresh would be much appreciated.

Many thanks

Marc
