Yes, I searched on "python dict comprehension" because I'd gottion the
idea somewhere that the "python" was necessary in this Brave New Google
world. I'll remember to omit "python" in the future when searching for
phrases most frequently found in Python. Boolean rules were so much
easier to learn and remember.

Well, it helped if you used 100 search results per page and other
various and sundry tools. But patience was good too. It depended how bad
you wanted the answer and how good a skim reader you are. Now I rarely
find anything I want unless I'm shopping for something to buy, but even
then I have to wade through all the garbage results intended to entice
the impulse buyer in me, which I ditched decades ago.

We can duke that out some other time. My illness is overcoming me fast
though, so it won't be right away.
