Just a short style question: When returning multiple return values, do
you use parenthesis?
E.g. would you write
def foo():
return 1, 2
a, b = foo()
or do you prefer
def foo():
return (1, 2)
(a, b) = foo()

My personal view: It's a matter of style; do whatever looks best to
you. Looking at my own code I'm not consistent in my choice. That said:
return item, cost # If I think of these as two distinct values
I'd be inclined to omit the parentheses.
return (x,y) # If I'm returning a point which I think
of as a single entity, I'd probably put them in,
# especially, for consistency,
if the rest of my code contains lots of `(x,y)`s, `(u,v)`s etc.
return (long-expression1, long-expression2)
# It might be hard to spot the
comma at first glance so the parentheses might help to recognise a tuple.
Best wishes
