Summary: [Python] Expose the offsets of a ListArray in python Key: ARROW-7031 URL: https://issues.apache.org/jira/browse/ARROW-7031 Project: Apache Arrow Issue Type: Improvement Components: Python Reporter: Joris Van den Bossche Assume the following ListArray: {code} In [1]: arr = pa.ListArray.from_arrays(offsets=[0, 3, 5], values=[1, 2, 3, 4, 5]) In [2]: arr Out[2]: <pyarrow.lib.ListArray object at 0x7f11de71c708> [ [ 1, 2, 3 ], [ 4, 5 ] ] {code} You can get the actual values as a flat array through {{.values}} / {{.flatten()}}, but there is currently no easy way to get back to the offsets (except from interpreting the buffers manually). We should probably add an {{offsets}} attribute (there is actually also a TODO comment for that). -- This message was sent by Atlassian Jira (v8.3.4#803005)
