I think it's just an cosmetic "problem" and probably the extra comma
is there for uniformity with the 2 lines above it - given it's a no-op
in this case (it generates no error after all) I'm inclined not to
change it. Also it might also be a standard for the person that wrote
the example to add an extra comma at the end of lists or tuples,
because sometimes it might be relevand (f.e. ('A',) is a tuple, and
the extra comma is needed there).
