Use curly braces to initialize a Set in Python

Question

I\'m learning python, and I have a novice question about initializing sets. Through testing, I\'ve discovered that a set can be initialized like so:

my_set          


        

Answer 1

There are two obvious issues with the set literal syntax:

my_set = {'foo', 'bar', 'baz'}

1. It's not available before Python 2.7

2. There's no way to express an empty set using that syntax (using {} creates an empty dict)

Those may or may not be important to you.

The section of the docs outlining this syntax is here.
