# Kvswap

{{< localstorage language language-py >}}

{{< button-pydoc path="apache_beam.transforms.util" class="KvSwap" >}}

Takes a collection of key-value pairs and returns a collection of key-value pairs
which has each key and value swapped.

## Examples

In the following example, we create a pipeline with a `PCollection` of key-value pairs.
Then, we apply `KvSwap` to swap the keys and values.

{{< highlight py >}}
{{< code_sample "sdks/python/apache_beam/examples/snippets/transforms/elementwise/kvswap.py" kvswap >}}
{{< /highlight >}}

{{< paragraph class="notebook-skip" >}}
Output `PCollection` after `KvSwap`:
