Values

Pydoc

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.

import apache_beam as beam

with beam.Pipeline() as pipeline:
  plants = (
      pipeline
      | 'Garden plants' >> beam.Create([
          ('🍓', 'Strawberry'),
          ('🥕', 'Carrot'),
          ('🍆', 'Eggplant'),
          ('🍅', 'Tomato'),
          ('🥔', 'Potato'),
      ])
      | 'Values' >> beam.Values()
      | beam.Map(print)
  )

Output PCollection after Values:

plants = [
    'Strawberry',
    'Carrot',
    'Eggplant',
    'Tomato',
    'Potato',
]
