chore: fix lint

[pulsejet]

Some comments for whoever (if anyone) is maintaining this

• VS Code has a flake8 extension that shows lint errors inline
• Commented-out code should never be checked in
• Docstrings go after the function declaration
• Docstrings are NOT multiline comments (please)
• Not sure why adj_list.py is ... .py
• eval is (extremely) evil
