Instances of **set and frozenset** provide the following operations:
```python |||
|---|---|
|len(s)|Return the number of elements in set s (cardinality of s).|
|x in s|Test x for membership in s.|
|x not in s|Test x for non-membership in s.|
|isdisjoint(other)|Return True if the set has no elements in common with other. Sets are disjoint if and only if their intersection is the empty set.|
|issubset(other)|Test whether every element in the set is in other.|
|set <= other|Test whether every element in the set is in other.|
|set < other|Test whether the set is a proper subset of other, that is, set <= other and set != other.|
|issuperset(other)|Test whether every element in other is in the set.|
|set >= other|Test whether every element in other is in the set.|
|set > other|Test whether the set is a proper superset of other, that is, set >= other and set != other.|
|union(*others)|Return a new set with elements from the set and all others. |
|set \| other \| ...|Return a new set with elements from the set and all others. |
|intersection(*others)|Return a new set with elements common to the set and all others.|
|set & other & ...|Return a new set with elements common to the set and all others.|
|difference(*others)|Return a new set with elements in the set that are not in the others.|
|set - other - ...|Return a new set with elements in the set that are not in the others.|
|symmetric_difference(other)|Return a new set with elements in either the set or other but not both.|
|set ^ other|Return a new set with elements in either the set or other but not both.|
|copy()|Return a shallow copy of the set.|
```
The following table lists operations **available for set** that do not apply to immutable instances of frozenset: The following table lists operations **available for set** that do not apply to immutable instances of frozenset:
