Generator question

[Timothy Wu]

Hi,

Using generator recursively is not doing what I expect:

def test_gen(x):
    yield x
    x = x - 1
    if x != 0:
        test_gen(x)

for item in test_gen(3):
    print item


This gives me a single number 3 and not printing 2 and 1 as I would expect.

What is wrong??

Timothy
