LazyWeb (sorry): learning python resources suitable for a first year electrical engineer student with a Raspberry Pi?

I'm helping out my nephew, who lives elsewhere. He wants to learn Python, but I'm drawing a blank on good resources. Dive into Python is more for experienced programmers. Learn Python the Hard Way costs money now (dammit). Raspberry Pi Foundation materials are a little below him. What else is out there, pls?
