I was just working with a generator for a tree that I wanted to skip
the first result (root node.)
There is already an obvious standard way to do this.
it = <whatever>
next(it) #toss first item
for item in it:
....
And it occurs to me, why do we need to do:
import sys
from itertools import islice
my_iter = islice(my_iter, 1, sys.maxint)
When we could simply add slice operations to generators?
for x in my_iter[1:]:
pass
1. islice works with any iterator; generator method would only work with
generators
2. iterator protocol is intentionally simple.
