Creating an empty set

Question

I have some code which tots up a set of selected values. I would like to define an empty set and add to it, but {} keeps turning into a dictionary. I have foun

Answer 1

A set literal is just a tuple of values in curly braces:

x = {2, 3, 5, 7}

So, you can create an empty set with empty tuple of values in curly braces:

x = {*()}

Still, just because you can, doesn't mean you should.

Unless it's an obfuscated programming, or a codegolf where every character matters, I'd suggest an explicit x = set() instead.
