What is the result of a yield expression in Python?
Solution 1:
You can also send values to generators. If no value is sent then x is None, otherwise x takes on the sent value. Here is some info: http://docs.python.org/whatsnew/2.5.html#pep-342-new-generator-features
>>> def whizbang():
for i in range(10):
x = yield i
print 'got sent:', x
>>> i = whizbang()
>>> next(i)
0
>>> next(i)
got sent: None
1
>>> i.send("hi")
got sent: hi
