- classmethod Check.isin(allowed_values, **kwargs)[source]#
Ensure only allowed values occur within a series.
This checks whether all elements of a data object are part of the set of elements of allowed values. If allowed values is a string, the set of elements consists of all distinct characters of the string. Thus only single characters which occur in allowed_values at least once can meet this condition. If you want to check for substrings use
Check.str_contains().
