But I don't think that OP cares about that :)Well it's nice to understand the differences between the two but this should be particularly helpful when I get round to the conversion (still working on pseudocode for the rest of it).i think it is (a quite simple one): every call to next() change its state, which allows it to move forward or to stop. This older article does a good job on outlining yield and generators too: yeah, but diesel/steam/jet/.. engines don't have spark plugs; while yield and generators are mutually dependent :) Btw, I love IBM developerworks articles :)no, but it will know what the value of "n" was last time.

Can't be 100% certain though. It's easy to show yourself that what I (and others) have said is true by working with the generator from your example in a more manual way. So for the list-comprehension-turned-generator you have 1 yield producing the top of the stack each time (replacing the top of the stack with the yield return value), and for the generator expression variant you yield the top of the stack (the integer) and then yield again, but now the stack contains the return value of the yield and you get None that second time.
