It's possible to write this yourself:
from itertools import islice
class ISlice:
def __init__(self, it):
self.it = iter(it)
def __getitem__(self, s):
if isinstance(s, slice):
return islice(self.it, s.start, s.stop, s.step)
# Presumably an integer
return islice(self.it, s, s+1)
if __name__ == "__main__":
a = range(10)
print(list(ISlice(a)[5:9]))
a = range(10)
print(list(ISlice(a)[5]))
I don't know whether I'd find it useful enough to be worth it, though...
