I won't know if this script works until I run it and see the errors but the comments won't start to generate until after all the posts so I can't debug that part until I've already created too much content.

Tests. And typing. And comments.
Tests can help you be sure that each piece is working as intended and that they're working together. You can also mock bits out or create a temporary database for local dev.
Adding typing and comments, especially docstrings will help others read your code more easily.
