Delete an Expectation

In this exercise, you'll practice deleting an Expectation from an Expectation Suite. The following variables have already been assigned:

expectation: the Expectation to delete
suite: the Expectation Suite containing expectation
validation_definition: the Validation Definition for the Expectation Suite
dataframe: the pandas DataFrame to run through the Validation Definition

Great Expectations and pandas are available as gx and pd, respectively.

Understand why Great Expectations (GX) is such a powerful tool for monitoring data quality. Get familiar with the basics of GX, including how to start a session using a Data Context, and how to load in a pandas dataframe using a Data Source, Data Asset, and Batch Definition.

Exercise 1: Create a Data Context Exercise 2: Create your Data Context Exercise 3: Sneak Peek into GX Exercise 4: Keyword Definitions Exercise 5: Connect to Data Exercise 6: Concept Review Exercise 7: Create a Data Source and Data Asset Exercise 8: Read Data in Batches Exercise 9: Create a Batch Definition and Batch Exercise 10: Inspect your Batch

Create and evaluate basic shape and schema Expectations. Validate your Expectations either individually, as part of an Expectation Suite with a Batch Definition, or using a Validation Definition.
