Synopsis
`xpressinsight.DataFrameBase.check_value(self, value: Any, columns: Optional[Iterable] = None, *, allow_duplicate_indices: Optional[bool] = None)`
Arguments

value | The potential value for this entity.
columns | If this is a DataFrame-type entity, an iterable specifying a subset of the columns to check; checks all columns if unset. Ignored for entity types that don't have columns.

This function may raise the following errors:

TypeError

  If the value has the wrong type for this entity.

KeyError

  If there is an issue with the indexing of the value.

ValueError
