[Edu-sig] Using IDLE with students

[kirby urner]

The subprocess idea is important I agree.

Also, psychologically, we would like students to see putting code in
a module as "canning for later" i.e. there's a strong prejudice against
thinking of the current session namespace as containing anything
vital to the operations of the module.  Picturing emailing the code to
a distant user who has never once booted Python is another mental
exercise one might use.
