how to run a file in powershell with python

[RomanEmpire]

Thank you both for your wisdom, I will not be using Powershell if that is the case. I'm a super novice with this (just learned command lines) and any and all advise is truely appreciated. with that said what would be the use of notepad++? if learn python the hard way is not well respected what would anyone recommend? I'm learning python to program raspberry pi and to do back end development.
