class great_expectations.expectations.core.expect_column_pair_values_to_be_in_set.ExpectColumnPairValuesToBeInSet(configuration: Optional[ExpectationConfiguration] = None)

Bases: great_expectations.expectations.expectation.ColumnPairMapExpectation

Expect paired values from columns A and B to belong to a set of valid pairs.

  • column_A (str) – The first column name

  • column_B (str) – The second column name

  • value_pairs_set (list of tuples) – All the valid pairs to be matched

Keyword Arguments

ignore_row_if (str) – “both_values_are_missing”, “either_value_is_missing”, “neither”

Other Parameters
  • result_format (str or None) – Which output mode to use: BOOLEAN_ONLY, BASIC, COMPLETE, or SUMMARY.

  • include_config (boolean) – If True, then include the expectation config as part of the result object. catch_exceptions (boolean or None): If True, then catch exceptions and include them as part of the result object. meta (dict or None): A JSON-serializable dictionary (nesting allowed) that will be included in the output without modification.
