class great_expectations.expectations.set_based_column_map_expectation.SetBasedColumnMapExpectation(configuration: Optional[great_expectations.core.expectation_configuration.ExpectationConfiguration] = None)#

Base class for SetBasedColumnMapExpectations.

SetBasedColumnMapExpectations facilitate set-based comparisons as the core logic for a Map Expectation.

Example Definition:

    set_camel_name = SolfegeScale
    set_ = ['do', 're', 'mi', 'fa', 'so', 'la', 'ti']
    set_semantic_name = "the Solfege scale"
    map_metric = SetBasedColumnMapExpectation.register_metric(
        set_camel_name=set_camel_name,
        set_=set_
)

Parameters:

  • set_camel_name (str) – A name describing a set of values, in camel case.

  • set (str) – A value set.

  • set_semantic_name (optional[str]) – A name for the semantic type representing the set being validated..
