ExpectColumnMaxToBeBetween
(configuration: Optional[ExpectationConfiguration] = None)¶ Bases:
great_expectations.expectations.expectation.ColumnExpectation
Expect the column max to be between an min and max value
expect_column_max_to_be_between is a
column_aggregate_expectation
.- Parameters
column (str) – The column name
min_value (comparable type or None) – The minimum number of unique values allowed.
max_value (comparable type or None) – The maximum number of unique values allowed.
- Keyword Arguments
parse_strings_as_datetimes (Boolean or None) – If True, parse min_value, max_values, and all non-null column values to datetimes before making comparisons.
output_strftime_format (str or None) – A valid strfime format for datetime output. Only used if parse_strings_as_datetimes=True.
strict_min (boolean) – If True, the minimal column minimum must be strictly larger than min_value, default=False
strict_max (boolean) – If True, the maximal column minimum must be strictly smaller than max_value, default=False
- 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.
Notes
These fields in the result object are customized for this expectation:
{ "observed_value": (list) The actual column max }
min_value and max_value are both inclusive unless strict_min or strict_max are set to True.
If min_value is None, then max_value is treated as an upper bound
If max_value is None, then min_value is treated as a lower bound

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 neccessary configuration arguments have been provided for the validation of the expectation.
- Parameters
configuration (OPTIONAL[ExpectationConfiguration]) – An optional Expectation Configuration entry that will be used to configure the expectation
- Returns
True if the configuration has been validated successfully. Otherwise, raises an exception
