Okay, now you're asking a question in a reasonable way, so we can answer :)
The thing you're confused at is that it's not the parentheses that
create a tuple. Parentheses merely group.
>>> 'hello', 'bonjour'
('hello', 'bonjour')
>>> 'hello',
('hello',)
One-element tuples are perfectly possible, but you MUST have a comma,
so you have one at the end. The trailing comma is perfectly legal (and
ignored) on larger tuples.
>>> 'hello', 'bonjour',
('hello', 'bonjour')
