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

["Joris Van den Bossche (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-9997?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17196186#comment-17196186 ] 

Joris Van den Bossche commented on ARROW-9997:
----------------------------------------------

Personnally, I think moving away from the mapping API is quite a usability regression. Would it be a possibility to still provide that as the default, but have a alternative way to get a field by position? 
(in a similar way, Table and Schema also work like that, they raise when getting a field by name and the name is duplicated, but you still can get a field by name)

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