I also think it effectively solves the switch-statement problem:

if (getresponse() as answer) == 'yes': doit() elif answer == 'no': skipit() elif answer == 'maybe' okaythen() That’s Pythonic enough for jazz!

Is it just me or since when has the following Python code fallen out of favor?

answer = get_response() if answer == 'yes': do_it() elif answer == 'no': skip_it() elif answer == 'maybe' okay_then()

I really don't see anything I would want to optimize here. Not even a single bit. But as said that might just be me.

What I like about this code is:

  1. symmetry: all ifs are equally structured
  2. classic IPO model: first get input, then process (, then output)
