wjones127 opened a new pull request #9073:
URL: https://github.com/apache/arrow/pull/9073


   These changes make it easier to get an Array / Field from a 
`pyarrow.RecordBatch` by name, mimicking the existing functionality of the 
`pyarrow.Table` API.
   
   ```python
   # Existing pyarrow.Table API:
   table.field('my_column') # returns pyarrow.Field
   table.column('my_column') # returns pyarrow.ChunkedArray
   table['my_column'] # returns pyarrow.ChunkedArray
   
   # New pyarrow.RecordBatch API:
   batch.field('my_column') # returns pyarrow.Field
   batch.column('my_column') # returns pyarrow.Array
   batch['my_column'] # returns pyarrow.Array
   ```
