In python >= 2.4, you can define a function like this:
def truncate(iterable, n=1):
iterator = iter(iterable)
for i in iterator:
if n == 0:
yield iterator
return
yield i
n -= 1
>>> a, b, c, tail = truncate([1,2,3,4,5,6], 3)
>>> a
1
>>> b
2
>>> c
3
>>> tail
<listiterator object at 0x78990>
>>> list(tail)
[5, 6]
