There are a lot of us who use a test-first process:
    Write a unit test, watch it fail, fix the code til the test passes.
If the project is smallish, I'll have Idle to experiment a bit (as
others have said, for checking boundary cases on standard module

window A: test file editor
window B: module editor
window C: command line for running tests.
window D: idle for checking boundary conditions on Python modules.

My typical cycle is change file (either window A or B), save that,
re-run the unit test in window C.  Every now and then (when test are
succeeding), I check in the sources (and the tests).  Before I was
doing this, I explored my module with Idle, but that often left me
with too few test cases.
