The real (and no doubt PSU-intended) use of list comprehensions is, of
course, to finesse Python's _apparent_ lack of assignment-in-expression.
Instead of coding a vulgar, typo-prone, hoi-polloi oriented:
while x = bluh():
whatever(x)
you get to code an elegant, refined, hoi-oligoi reserved:
while [ x for x in [bluh()] if x ] :
whatever(x)
(I'm told Beretta makes excellent small arms, should you need one...).
