Write up a Conditional Expectation

Taking a look at the Shein dataset, you can probably come up with a few Conditional Expectations. One such Expectation could be that the star_rating of a product should be 0.0 if the product has no reviews. Let's practice establishing this Conditional Expectation.

A Batch connected to the Shein Footwear dataset has already been created and assigned to the variable batch. Great Expectations and pandas are available as gx and pd, respectively.
