[Python] Improve ergonomics of compute functions #25538
Description
Introspection of exported compute functions currently yield suboptimal output:
>>> from pyarrow import compute as pc
>>> pc.list_flatten
<function pyarrow.compute._simple_unary_function.<locals>.func(arg)>
>>> ?pc.list_flatten
Signature: pc.list_flatten(arg)
Docstring: <no docstring>
File: ~/arrow/dev/python/pyarrow/compute.py
Type: function
>>> help(pc.list_flatten)
Help on function func in module pyarrow.compute:
func(arg)The function should ideally have:
- the right global name
- an appropriate signature
- a docstring
