[PATCH] Fix accessing a function's fields (parameters) from Python (PR 18073)

The patch looks good to me, although I am not one of the main Python
maintainers. Normally, I'd ask the author to wait an extra week for
additional comments, but since you've already waited a month, I think
it's only fair to give you the go ahead to push. If there are comments
with your code, we can handle them then.

Thanks also adding the tests. You probably know this, but this is
always appreciated.

Thanks!
