> It's not at all obvious how to get a particular field from a StructType from
> it's API page:
> https://arrow.apache.org/docs/python/generated/pyarrow.StructType.html#pyarrow.StructType
> We should add an example:
> {code:python}
> struct_type = pa.struct({"x": pa.int32(), "y": pa.string()})
> struct_type[0]
> # pyarrow.Field<x: int32>
> pa.schema(list(struct_type))
> # x: int32
> # y: string
> {code}
