In addition to the other answers there is the option of just creating
the function in a Python module outside Postgres and doing:

from some_module import f

Which would seem to address this(from the SO post):

"This can be done using t = plpy.execute("select f1()"), but I want, if
it is possible, call it as a normal Python function to avoid type
conversions (for example jsonb, etc)."

The downside being you have a dependency outside the database.
