             Summary: [Python] Allow type inference for struct arrays
                 Key: ARROW-2074
                 URL: https://issues.apache.org/jira/browse/ARROW-2074
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
            Reporter: Antoine Pitrou
            Assignee: Antoine Pitrou


Support inferring a struct type in a {{pa.array}} call, if a sequence of dicts 
(or dict of sequences?= is given. Of course, this could mean that the wrong 
field order may be inferred, though on Python 3.6+ dicts retain ordering until 
the first deletion.
