# Joining two sets in Python

We can join two sets in Python using either the `update(~)` method or the `union(~)` method.

# Examples

## Update method

Consider the following two sets:

``` A = {1, 2, 3}B = {3, 4, 5} ```

To add all elements of set `B` to set `A`:

``` A.update(B)print(A) {1, 2, 3, 4, 5} ```

Note that here we are modifying set `A` in place.

## Union method

Consider the following two sets:

``` A = {1, 2, 3}B = {3, 4, 5} ```

To return a new set with elements from set `A` and set `B`:

``` A.union(B) {1, 2, 3, 4, 5} ```
