Python's set.intersection(~) method returns a new set with elements common to all the provided sets.

Parameters

1. sets | set | optional

The sets to return common elements for.

Return value

A new set with elements common to the input sets.

Examples

Basic usage

To return a set of all elements common to sets A, B, C:

a = {'dog', 'cat', 'pig'}
b = {'frog', 'fish', 'dog'}
c ={'mouse', 'dog'}

a.intersection(b, c)
{'dog'}

As 'dog' is common to all three sets, a set containing 'dog' is returned.
