Really short answer:
def f():
yield 1
yield 2
yield 3
for x in f(): print x,
# should print 1 2 3
def f():
for x in xrange(10):
yield x
for x in f(): print x,
# should print 0 1 2 3 4 5 6 7 8 9
note that this won't work;
def f():
for x in xrange(10):
for y in xrange(10):
yield (x,y)
yield just doesn't work right with multiple levels of loops. i had to
discover that the hard way.
