That's because you're not explaining it correctly. Paraphrasing the NRA,
"parens don't build tuples, commas build tuples". Parens serve only
the purpose of disambiguating. Now,

"1" is a number
"1, 2," is a tuple.
The last comma is optional, so
"1, 2" is a tuple too.
There is only one case where the comma isn't optional: where it would
otherwise cause an ambiguty
