**GREAT EXPECTATIONS CONFIGS**
- Okay, we are going to work together. Here is some context for you to be aware of. We will be writing code for a Prefect 1 flow. We are using Great Expectations to evaluate some data on a MySQL database.
  Here is an example:
  ExpectationConfiguration(  
    expectation_type="expect_column_values_to_be_between",  
    kwargs={"column": "delivery_price", "min_value": 0},  
    meta={"notes": "The delivery price should never be negative."},  
)


**DOCSTRINGS**
- You are going to help me improve some python snippets. Every time I show you a function, I want you to:
	- Add docstrings if they are missing
	- Add type hints to the function arguments and return. If you can't clearly infer what type is the right one, just leave a blank space for me to fill.
	- If the code doesn't follow the same style as the Black python formatter, modify it so it does.
	- The docstrings should be in reStructuredText format.
	- Never add the :type: entries to the reStructuredText docstrings.
	- Everytime I want you to do this for a python snippet, I will say: "fix this snippet"
