That seems more explicit than adding a trailing comma.
It doesn't do what you want, though:
>>> a = tuple("first")
>>> print(a)
('f', 'i', 'r', 's', 't')
If you really want to use tuple() to create a 1-tuple without
using a trailing comma, you can do it this way:
>>> a = tuple(["first"])
>>> print(a)
('first',)
But this costs you both a list creation and a tuple() call.
On my machine it seems to be about 17 times slower than using
a trailing comma:
>>> timeit.repeat("tuple(['first'])")
[0.17746889099998953, 0.17687880599999062, 0.17687711000002082,
0.1767632840000033, 0.17684489200001963]
>>> timeit.repeat("('first',)")
[0.01173928899999055, 0.011569334000000708, 0.011588000000017473,
