I generally prefer to do this with generators rather than mutation.
I.e. instead of
blech = []
while some_condition():
yuck = some mess
blech.append(yuck)
result = ''.join(blech)
I like
def gen_blech():
while some_condition():
yield (some mess)
result = ''.join(gen_blech())
It just seems cleaner. YMMV. Of course when "some mess" is a single
expression instead of multiple statements, it may be possible to use
a genexp without the auxiliary function.
