So I've been reading up on all the new stuff in PEP 342, and trying to
understand its potential. So I'm starting with a few simple examples to
see if they work as expected, and find they dont.
I'm basically trying to do the following:
for x in range(10):
print x*2
but coroutine-style.
My initial try was:
>>> def printrange():
... for x in range(10):
... x = yield x
... print x
...
>>> g = printrange()
>>> for x in g:
... g.send(x*2)
...
0
1
None
4
3
None
8
5
None
12
7
None
16
9
None
>>>
Now, I was expecting that to be 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20.
What am I missing here?
