Broken markdown in section 7 #128
Description
The rendered notebook for section 7 shows Markdown syntax:
When you choose a name, remember that you cannot use a reserved keyword, and that it is advisable to work with a descriptive name. The Python community has [guidelines for naming functions][pep8-func]. It is recommended to come up with function names that are “lowercase, with words separated by underscores to improve readability”. [pep8-func]: https://peps.python.org/pep-0008/#function-and-variable-names
The [pep8-func]: needs to be on a separate line.
