Description: Given a list of values and a constant scalar, determine whether each of the values is less than or equal to the scalar. If a value is equal to the scalar, return `True`. Examples: >>> less_than_equal_to_scalar = LessThanEqualToScalar(value=2) >>> less_than_equal_to_scalar([3, 1, 2]).tolist() [False, True, True] """ name = "less_than_equal_to_scalar" input_types = [ColumnSchema(semantic_tags={"numeric"})] return_type = ColumnSchema(logical_type=BooleanNullable) compatibility = [Library.PANDAS, Library.DASK, Library.SPARK]
