Hello,

I believe there's a mistake in the documentation of library/warnings.

https://docs.python.org/3.8/library/warnings.html#warnings.warn

"This function raises an exception if the particular warning issued is changed into an error by the warnings filter see above."

I think "see above" should be enclosed in brackets (or maybe completely removed as there is already a "(see above)" in the same text block).

Regards.
