Expect the column entries to be strings with length between a minimum value and a maximum value (inclusive).

This expectation only works for string-type values. Invoking it on ints or floats will raise a TypeError.

expect_column_value_lengths_to_be_between is a Column Map Expectation.

Args:

• column (str): The column name.
• min_value (int or None): The minimum value for a column entry length.
• max_value (int or None): The maximum value for a column entry length.

Keyword Args:

• mostly (None or a float between 0 and 1): Successful 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.
• 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, include_config, catch_exceptions, and meta.

Notes:

• min_value and max_value are both inclusive.
• If min_value is None, then max_value is treated as an upper bound, and the number of acceptable rows has no minimum.
• If max_value is None, then min_value is treated as a lower bound, and the number of acceptable rows has no maximum.
