ScalarInequality
Ensure an inequality between the column_name column and a scalar value.
column_name
value
The transformation works by creating a column with the difference between the column_name and value and storing it in the column_name’s place. The reverse transform adds the difference column and the value to reconstruct the column_name.
column_name (str) – Name of the column to compare.
relation (str) – Describes the relation between column_name and value. Choose one among '>', '>=', '<', '<='.
'>'
'>='
'<'
'<='
value (float or datetime) – Scalar value to compare.
__init__
Initialize self. See help(type(self)) for accurate signature.
Methods
__init__(column_name, relation, value)
Initialize self.
