Python's `set.symmetric_difference(~)` method returns a new set with elements that are contained in either the specified set or sets specified in `others` but not both.

# Parameters

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

The other sets to compare elements of the specified set with.

# Return value

A new set with elements that are contained in either the specified set or sets specified in `others` but not both.

# Examples

## Basic usage

To check elements contained in either set `a` or set `b` but not both:

``` a = {'dog', 'cat'}b = {'sheep', 'dog'}a.symmetric_difference(b) {'cat', 'sheep'} ```

A set containing `'cat'` and `'sheep'` are returned as they are only present in either set `a` or `b` and not both.
