             Summary: [Python] Partitioning.dictionaries in case of a subset of fields are dictionary encoded
                 Key: ARROW-16113
                 URL: https://issues.apache.org/jira/browse/ARROW-16113
             Project: Apache Arrow
          Issue Type: Test
          Components: Python
            Reporter: Joris Van den Bossche


Follow-up on ARROW-14612, see the discussion at https://github.com/apache/arrow/pull/12530#discussion_r841760449

ARROW-14612 changes the return value of the {{dictionaries}} attribute from None to a list in case some of the partitioning schema fields are not dictionary encoded. 

But this can result in a non-clear mapping between arrays in {{Partitioning.dictionaries}} and fields in {{Partitioning.schema}}
