moses

emlib.misc.moses(pred, seq)

Divides seq into two lists: filter(pred, seq), filter(not pred, seq)

Parameters:

• pred (Callable[[TypeVar(T)], bool]) – a function predicate

• seq (Iterable[TypeVar(T)]) – the seq. to divide

Return type:

tuple[list[TypeVar(T)], list[TypeVar(T)]]

Returns:

a tuple (true_elements, false_elements), where true_elements contains the items in seq for which pred evaluates to true, and false_elements contains the rest

Example:

>>> moses(lambda x:x > 5, range(10))
([6, 7, 8, 9], [0, 1, 2, 3, 4, 5])
