---------------------------------------------
Summary: [Python] Construct MapArray from sequence of dicts
(instead of list of tuples)
Key: ARROW-17832
URL: https://issues.apache.org/jira/browse/ARROW-17832
Project: Apache Arrow
Issue Type: Improvement
Components: Python
Reporter: Joris Van den Bossche
>From https://github.com/apache/arrow/issues/14116
Creating a MapArray from a python sequence currently requires lists of tuples
as values:
```
arr = pa.array([[('a', 1), ('b', 2)], [('c', 3)]], pa.map_(pa.string(),
pa.int64()))
```
While I think it makes sense that the following could also work (using dicts
instead):
```
arr = pa.array([{'a': 1, 'b': 2}, {'c': 3}], pa.map_(pa.string(), pa.int64()))
```
