Python's set.union(~) method returns a new set with elements from all the provided sets.

Parameters

1. sets | set | optional

The sets from which we will include elements from.

Return value

A new set with elements from all the provided sets.

Examples

Basic usage

To return a new set with all elements from sets a, b, c:

a = {'dog', 'cat'}
b = {'sheep', 'dog'}
c ={'mouse', 'dog'}

a.union(b, c)
{'cat', 'dog', 'mouse', 'sheep'}

We can see that we return a new set containing all distinct elements from sets a, b, c. By definition, Sets do not allow duplicates values, hence 'dog' only appears once in the returned set.
