This code defines a `router` object with the prefix `/comments` and the tag `"Comments"`. The router contains the following endpoints:



Note: You'll need to define the `Comment`, `CommentCreate`, and `CommentResponse` models and schemas in the appropriate files (`models.py` and `schemas.py`) for this code to work correctly.
