Microsoft Store in Windows 10 has the Python 3.7 and 3.8 packages (prepared by PSF itself) with some limitations, which shouldn't matter for beginner users. So it's basically one click install.
The issues has to do with the way Microsoft Store apps are sandboxed within the environment, to quote:
Because of restrictions on Microsoft Store apps, Python scripts may not have full write access to shared locations such as TEMP and the registry. Instead, it will write to a private copy. If your scripts must modify the shared locations, you will need to install the full installer.
