Ah, you youngsters... :-)
Using a bool to index into a list used to be the standard idiom, before the
ternary if was added to the language. So I don't consider it "weird",
especially as a lot of my code still supports Python 2.4 which doesn't
include the ternary if.
Sometimes, instead of a list, I'll use a dict:
{True: value1, False: value2}[flag]
to emulate ternary if.
