successive

class iteration_utilities.successive(iterable, times=2)

Like the recipe for pairwise but allows to get an arbitrary number of successive elements.

Parameters

iterableiterable

Get the successive elements from this iterable.

timesint, optional

The number of successive elements. Default is 2.

Returns

successive_elementsgenerator

The successive elements as generator. Each element of the generator is a tuple containing times successive elements.

Examples

Each item of the iterable is returned as tuple with times successive items:

>>> from iteration_utilities import successive
>>> list(successive(range(5)))
[(0, 1), (1, 2), (2, 3), (3, 4)]

Varying the times can give you also 3 successive elements:

>>> list(successive(range(5), times=3))
[(0, 1, 2), (1, 2, 3), (2, 3, 4)]
>>> list(successive('Hello!', times=2))
[('H', 'e'), ('e', 'l'), ('l', 'l'), ('l', 'o'), ('o', '!')]

__length_hint__()

Tries to estimate for the length of the instance (returns 0 if an estimation is not possible).

times

(int) The number of successive items (readonly).
