[jira] [Commented] (ARROW-9997) [Python] StructScalar.as_py() fails if the type has duplicate field names

["Krisztian Szucs (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-9997?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17209862#comment-17209862 ] 

Krisztian Szucs commented on ARROW-9997:
----------------------------------------

I find this issue a bit pressing before the release, but I'm not sure about the desired resolution. Perhaps returning with a multimap/multidict like object from {{scalar.as_py()}} would work (although it can cause backward incompatibilities if users expect dictionary instances). 

[~apitrou] [~jorisvandenbossche] thoughts?

> {{StructScalar}} currently extends an abstract Mapping interface. Since the type allows duplicate field names we cannot provide that API.
