Note: you *may* import the math module, for sqrt, but remember pow is in
__builtins__ so (1 + pow(5, 0.5))/2 will work.

I liked your smooth transition from shell mode to Run in module mode
while keeping the shell open in __main__.  There's no restart in this
picture, we you're free to keep treating the module almost like a
generator in that it yields control back to the shell (after printing).

>From there it's a quick jump to explaining how a module might run
top level (as __main__), with no interactive session for a launch pad.
Put everything you'll need in the suitcase.  Just an empty hotel room
(Python interpreter + we hope Standard Library) on the other end.
