Takes a collection of key-value pairs, and returns the value of each element.

## Example

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

```py
{% github_sample /apache/beam/blob/master/sdks/python/apache_beam/examples/snippets/transforms/element_wise/values.py tag:values %}```

Output `PCollection` after `Values`:

```
{% github_sample /apache/beam/blob/master/sdks/python/apache_beam/examples/snippets/transforms/element_wise/values_test.py tag:plants %}```
