Yes, ummm seems soo... err.
This is one of those Python isn't quite consistent for practical reasons
area. I don't create empty tuples that way very often, but [] is to ()
is to {} is pretty obvious so I don't really have a good excuse.
>>> (1)
1
>>> ()
()
>>> (((((1)))))
1
>>> ((()))
()
Well in my previous explanation I *mean* it to be empty parenthesis.
Does that help?
