I'm starting a new thread for this topic, so as not to hijack the one
started by Steve Howell's excellent post titled "ten small Python
programs".
In that thread, there was a suggestion that these examples should
conform to PEP-8's style recommendations, including use of
lower_case_with_underscore
Out of curiosity, how does this style jibe with the latest embracing
