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.
- times
int, 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
tuplewith 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
0if an estimation is not possible).
