The built-in set() function returns a new set based on an optional iterable object such as a list

Syntax

set(iterable)

The iterable parameter is optional. If nothing is passed, an empty set is created.

Example

my_set = set()
print(my_set)
print(type(my_set))
my_set = set(["A", "B", "C"])
print(my_set)

The following output will look like this:

set()
<class 'set'>
{'C', 'B', 'A'}
