Weston Pace commented on ARROW-14060:
-------------------------------------
I thought I could already do this by specifying the data type:
{code:python}
arr = pa.array([<uuid-object>, ..], my_uuid_extension_type)
{code}
So I was just thinking we need:
{code:python}
tab = pa.Table.from_dict(my_table, {<uuid-type>: my_uuid_extension_type })
{code}
> [Python] Allow Table.from_pydict to specify a type mapper for extension types

> An example use case would be registering a type mapper that maps from UUID to
> a custom extension type or registering an extension type for `complex`.
> However, it could be used for builtin types as well (e.g. mapping all `int`
> to `pa.int8()`)
