Python's `set.difference(~)` method returns a new set with elements that are contained in the particular specified set, but not in other sets.

# Parameters

1. `others` | `set(s)`

The other sets.

# Return value

A new set with elements that are contained in the particular specified set, but not in other sets.

# Examples

## Basic usage

To return elements contained in set `a`, but not contained in sets `b` or `c`:

``` a = {'dog', 'cat'}b = {'sheep', 'dog'}c ={'mouse', 'tiger'}a.difference(b, c) {'cat'} ```

The returned set contains `'cat'` as it is part of set `a`, but not part of sets `b` or `c`.
