I've already written a python program, I have no idea how to usb mount so would it be easier putting it on my microsd card used to boot my pi up? My pi is using raspbian-jessie-lite and i don't understand any commands in great depth. So all I want to do is run a python file off my raspberry pi.. please help.
connect via sftp(FileZilla) to your rasppberry pi and just upload a file. then connect to the raspberry via ssh and
cd to the path where you uploaded your file and run command
