Are there more ways to define a tuple with only one item?

Question

I know this is one way, by placing a comma:

>>> empty = ()
>>> singleton = 'hello',    # <-- note trailing comma
>>> len(empty)
0
>>> len(singleton)
1
>>> singleton
('hello',)

Answer 1

>>> tuple(['hello'])
('hello',)

But the built-in syntax is there for a reason.
