Support Language Python in dbt UDFs

[ShaneMazur]

Current state

Creating a python UDF using the dbt functions feature produce the error:

Materialization "materialization_function_default" only supports languages ['sql']; got "python"

Request

1. Support this functionality as it is supported in various other dbt adapters
2. If necessary I can contribute this but would like to know if there are plans/recommended path for implementation I can refer to.

Shipped in #1336 (merged 2026-03-03). The Python UDF materialization now lives at dbt/include/databricks/macros/materializations/functions/scalar.sql and the "Materialization 'materialization_function_default' only supports languages ['sql']" restriction is gone. Closing as completed — reopen if you hit anything after upgrading past the release that includes it.
