Cleanest way to get last item from Python iterator
If you are using Python 3.x:
*_, last = iterator # for a better understanding check PEP 448print(last)if you are using python 2.7:
last = next(iterator)for last in iterator: continueprint last
Side Note:
Usually, the solution presented above is what you need for regular cases, but if you are dealing with a big amount of data, it's more efficient to use a deque of size 1. (source)
from collections import deque#aa is an interatoraa = iter('apple')dd = deque(aa, maxlen=1)last_element = dd.pop()
Use a deque of size 1.
from collections import deque#aa is an interatoraa = iter('apple')dd = deque(aa, maxlen=1)last_element = dd.pop()
