[jira] [Created] (ARROW-13612) [Python] Allow specifying a custom type for converting ExtensionScalar to python object

Joris Van den Bossche created ARROW-13612:
---------------------------------------------

             Summary: [Python] Allow specifying a custom type for converting ExtensionScalar to python object
                 Key: ARROW-13612
                 URL: https://issues.apache.org/jira/browse/ARROW-13612
             Project: Apache Arrow
          Issue Type: Test
          Components: Python
            Reporter: Joris Van den Bossche


As a follow-up on ARROW-13541 (https://github.com/apache/arrow/pull/10904#discussion_r686609844), we could have a mechanism that the ExtensionType can control the behaviour of {{ExtensionScalar.as_py()}} method.

Similarly as we have {{\_\_arrow_ext_class\_\_}} for using an ExtensionArray subclass for the array object, we could indeed have a way to specify a custom scalar wrapper.
