In a block comment, I want to reference a URL that is over 80 characters long.
What is the preferred convention for displaying this URL?
I know bit.ly is an option, but the URL itself is descriptive. Shortening it and then having a nested comment describing the shortened URL seems like a crappy solution.
You can use the # noqa at the end of the line to stop PEP8/Flake8 from running that check.  This is allowed by PEP8 via:

Special cases aren't special enough to break the rules.
How should I format a long url in a python comment and still be PEP8 compliant
