partition¶

iteration_utilities.partition(iterable, pred=None)¶

Use a predicate to partition entries into False entries and True entries.

Parameters:

iterableiterable: Iterable to partition.
predcallable or None, optional: The predicate which determines the partition. Default is None.

Returns:

false_valueslist: An list containing the values for which the pred was False.
true_valueslist: An list containing the values for which the pred was True.

Examples

>>> from iteration_utilities import partition
>>> def is_odd(val): return val % 2
>>> partition(range(10), is_odd)
([0, 2, 4, 6, 8], [1, 3, 5, 7, 9])

Warning

In case the pred is expensive then partition() can be noticeable faster than ipartition().
