How to store a dictionary with SQLAlchemy and SQLite3

Question

I'm trying to store a column with a dictionary data type. I've CTRL + F in the docs but the only mention of 'dictionary' doesn't help.

https://docs.sqlalchemy.org/en/13/core/type_basics.html

Here is an example I have of an integer data type if you need a reference:

friend_code = db.Column(db.Integer, nullable=False)
