Section 6.6 of the Apache Beam Python programming guide lacks examples

[damccorm]

In the section "Using Schema Transforms" of the Python programming guide, which can be found here, there are missing examples. e.g.

Nested fields

Individual nested fields can be specified using the dot operator. For example, to select just the postal code from the shipping address one would write

Wildcards

The * operator can be specified at any nesting level to represent all fields at that level. For example, to select all shipping-address fields one would write

These paragraphs are eerily similar to the ones that can be found on the Java programming guide, but they have their corresponding examples.

#23224 addresses the Select and GroupBy transforms, that are supported in Python. But there's still some inconsistencies in the "schema transforms" docs, e.g. it discusses DropFields, AddFields, etc.. that only exist in Java. We should also add languages switches for those sections. Leaving this open to track that.

Hi @damccorm!
I'm a GSoC 2026 applicant interested in contributing to Apache Beam. Is this issue still relevant and open for contribution? If so, I'd love to work on it!
