To boil down the issue to a minimal example, creating a MapArray from a
python sequence currently requires a list of tuples:
```
arr = pa.array([[('a', 1), ('b', 2)], [('c', 3)]], pa.map_(pa.string(),
pa.int64()))
```
While I think it certainly makes sense that the following could also work
(using dicts instead, which would avoid the manual conversion step from dicts
to list of tuples in advance):
```
arr = pa.array([{'a': 1, 'b': 2}, {'c': 3}], pa.map_(pa.string(),
pa.int64()))
```
I opened https://issues.apache.org/jira/browse/ARROW-17832 to track this.
