ExpectTableColumnsToMatchOrderedList(configuration: Optional[ExpectationConfiguration] = None)

Expect the columns to exactly match a specified list.

class great_expectations.expectations.core.expect_table_columns_to_match_ordered_list.ExpectTableColumnsToMatchOrderedList(configuration: Optional[ExpectationConfiguration] = None)

Bases: great_expectations.expectations.expectation.TableExpectation

Expect the columns to exactly match a specified list.

expect_table_columns_to_match_ordered_list is a expectation, not a column_map_expectation or column_aggregate_expectation.


column_list (list of str) – The column names, in the correct order.

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

  • include_config (boolean) – If True, then include the expectation config as part of the result object. For more detail, see include_config.

  • catch_exceptions (boolean or None) – If True, then catch exceptions and include them as part of the result object. For more detail, see catch_exceptions.

  • meta (dict or None) – A JSON-serializable dictionary (nesting allowed) that will be included in the output without modification. For more detail, see meta.


An ExpectationSuiteValidationResult

Exact fields vary depending on the values passed to result_format and include_config, catch_exceptions, and meta.

metric_dependencies = ['table.columns']
success_keys = ['column_list']
domain_keys = ['batch_id', 'table', 'row_condition', 'condition_parser']
validate_configuration(self, configuration: Optional[ExpectationConfiguration])

Validates that a configuration has been set, and sets a configuration if it has yet to be set. Ensures that necessary configuration arguments have been provided for the validation of the expectation.


configuration (OPTIONAL[ExpectationConfiguration]) – An optional Expectation Configuration entry that will be used to configure the expectation


True if the configuration has been validated successfully. Otherwise, raises an exception
