Values

{% include button-pydoc.md path=“apache_beam.transforms.util” class=“Values” %}

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.

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

Output `PCollection` after `Values`:

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