Nope. The list comprehension syntax creates lists.

This contains no commas, so I don't know why you think it has anything
to do with a tuple.

Bear in mind that parentheses have nothing to do with the syntax for
creating a tuple; the parentheses merely determine parsing order, and
can enclose any expression.

    tuple(range(1, 10))
