Correct. The comma is needed on a single-element tuple so that Python
can distinguish between something that's in parentheses for grouping
(e.g., a mathematical expression where you'd want to group things to
avoid operator precedence) and something that's in parentheses to be a
tuple.
And technically, the comma is what makes a tuple, not the parentheses.
For example, this function returns a tuple:
def return_tuple():
return 'foo', 'bar', 'baz'
