In this page: https://docs.python.org/3/library/urllib.parse.html#module-urllib.parse

In the code snippet under urllib.parse.urlparse:
urlparse("scheme://netloc/path;parameters?query#fragment")
ParseResult(scheme='scheme', netloc='netloc', path='/path;parameters', params='',
query='query', fragment='fragment')

This shows the parameters component of the URL being placed (in the output named tuple) onto the end of .path, not into .params. Seems likely that this is an oversight. But I don't have enough experience with the code to know for sure.
