allany()

Returns a function that checks if any of the given predicates return True for every item in the given list.

Implementation

Parameters: *preds: Callable[[Any], bool] Zero or more predicate functions to test. Returns: Callable[[List[Any]], bool] A function that takes a list and returns True if every item in the list satisfies at least one of the given predicates, False otherwise.

Example

                            def is_even(x):
    return x % 2 == 0
def is_positive(x):
    return x > 0
is_even_and_positive = allany(is_even, is_positive)
is_even_and_positive([2, 4, 6])  # True
is_even_and_positive([1, 3, 5])  # False
                        

Expected output:
