ExpectColumnValuesToNotMatchRegex(configuration: Optional[ExpectationConfiguration] = None)

Expect column entries to be strings that do NOT match a given regular expression. The regex must not match any portion of the provided string. For example, “[at]+” would identify the following strings as expected: “fish”, “dog”, and the following as unexpected: “cat”, “hat”.

class great_expectations.expectations.core.expect_column_values_to_not_match_regex.ExpectColumnValuesToNotMatchRegex(configuration: Optional[ExpectationConfiguration] = None)

Bases: great_expectations.expectations.expectation.ColumnMapExpectation

Expect column entries to be strings that do NOT match a given regular expression. The regex must not match any portion of the provided string. For example, “[at]+” would identify the following strings as expected: “fish”, “dog”, and the following as unexpected: “cat”, “hat”.

expect_column_values_to_not_match_regex is a column_map_expectation.

Parameters
  • column (str) – The column name.

  • regex (str) – The regular expression the column entries should NOT match.

Keyword Arguments

mostly (None or a float between 0 and 1) – Return “success”: True if at least mostly fraction of values match the expectation. For more detail, see mostly.

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.

Returns

An ExpectationSuiteValidationResult

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