I thought that the following sequence
gl=0
def gen(x):
global gl
gl=x
yield x
s=gen(1)
suspends the generator just before the yield, so after the
assignment of s gl becomes 1.
Well, no. It is still zero. If I put
print "something"
before the yield, this doesn't get executed either. *EVERYTHING*
from the beginning until the yield gets executed only upon s.next().
Could you tell me please where can I read something in depth about the
semantics of generators? I feel a bit lost.
Thank you.
