A complete guide to mathematical set operations in Python. It can be used to compute standard math operations, such as intersection, union, difference, and symmetric difference.

Python’s `set`

is an unordered collection in Python. It can be used to compute standard math operations, such as intersection, union, difference, and symmetric difference. `Other`

collections — like list, tuple, and dictionary — don’t support set operations. `Dict`

view objects are set-like, which allows set operations. Refer to my story on Python sets.

This article will explore the mathematical operations supported by set objects in detail.

`union()`

`update()`

`intersection()`

`intersection_update()`

`difference()`

`difference_update()`

`symmetric_difference()`

`symmetric_difference_update()`

`isdisjoint()`

`issubset()`

`issuperset()`

Set operations can be done in two ways. By using the method or by using an operator.

Return a new setwith elements from the set and the `other`

. It’s performed by `union()`

or by using the `|`

operator

**Syntax**

`**union**(_*others_)`

`**set | other | ...**`
