ExpectColumnValueLengthsToEqual
(configuration: Optional[ExpectationConfiguration] = None)¶ Bases:
great_expectations.expectations.expectation.ColumnMapExpectation
Expect column entries to be strings with length equal to the provided value.
This expectation only works for string-type values. Invoking it on ints or floats will raise a TypeError.
expect_column_values_to_be_between is a
column_map_expectation
.- Parameters
column (str) – The column name.
value (int or None) – The expected value for a column entry length.
- 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.
