Joris Van den Bossche commented on ARROW-9997:
----------------------------------------------
Small correction: you can already get a field by index by passing an integer to
{{\_\_getitem\_\_}}:
{code}
In [19]: s = pa.scalar([('a', 1), ('b', 2), ('a', 3)], pa.struct([('a',
'int64'), ('b', 'int64'), ('a', 'int64')]))
In [20]: type(s)
Out[20]: pyarrow.lib.StructScalar
In [21]: s[0]
Out[21]: <pyarrow.Int64Scalar: 1>
{code}
The repr is also failing because that relies on {{as_py}}
> [Python] StructScalar.as_py() fails if the type has duplicate field names

> {{StructScalar}} currently extends an abstract Mapping interface. Since the
> type allows duplicate field names we cannot provide that API.
