intersperse¶
- class iteration_utilities.intersperse(iterable, e)¶
Alternately yield an item from the iterable and e. Recipe based on the homonymous function in the more-itertools package ([0]) but significantly modified.
- Parameters:
- iterableiterable
The iterable to intersperse.
- eany type
The value with which to intersperse the iterable.
- Returns:
- interspersedgenerator
Interspersed iterable as generator.
Notes
This is similar to
itertools.chain.from_iterable(zip(iterable, itertools.repeat(e)))
except that intersperse does not yield e as last item.References
Examples
A few simple examples:
>>> from iteration_utilities import intersperse >>> list(intersperse([1,2,3], 0)) [1, 0, 2, 0, 3] >>> list(intersperse('abc', 'x')) ['a', 'x', 'b', 'x', 'c']
- __length_hint__()¶
Tries to estimate for the length of the instance (returns
0
if an estimation is not possible).
- fillvalue¶
(any type) The interspersed fillvalue (readonly).
