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()
No. Parentheses are for grouping (and separation from surrounding code).
() and (1,) (can be though of as) group(ing) the a zero-width space
and one-comma pair respectively and separate them from the rest of the code.
