Why does json.dumps sometimes fail to serialize my Python object? or How can I customize the output f

The struggle is real. json.dumps won’t magically know how to serialize your custom class.

Quick fix: Add a `to_json()` method to your class that returns a dict. Then do `json.dumps(your_obj.to_json())`.

Or, if you’re feeling fancy, use `marshmallow` or `pydantic` for proper serialization. Overkill for debugging, though.
