Python and pip are probably installed correctly but haven't been added to your PATH environment variable yet. That means when you type in "pip ..." into your terminal, it doesn't know what a pip is or where to find it. To fix that press the windows key and type in "Edit the system environment variables" and open it. Near the bottom click "Environment Variables...". Now in the "System variables" section, select "Path", then click "Edit...". Finally click "New" on the right and type in the path to your Python installation (Default should be "C:\Program Files\Python313\"). Also add the scripts path (Default: "C:\Program Files\Python313\Scripts"). Click "OK" on all of the windows. Restart your terminal if you had it open and pip should now be working.
