changing generators at runtime

Mon, 20 Mar 2006 07:45:09 -0800

I want to build a generator that can update it's content during runtime, but I'm not sure whether what I'm doing works by mistake or works by purpose.

I've read PEP-255 about Generators, but nothing is mentioned about changing the inner space of the generator during runtime - this could mean that "it works by mistake" but from what I understand about generators - this behavior is a by-product of the algorithm.

I'm attaching an example of a generator and an iterator that are supposed to do produce the same output. The Iterator doesn't work and produces a RuntimeError while the Generator finishes the task successfully.

What do you think? is it safe to use the generator function? if not - do you have another safe approach to add items to a generator during runtime?

Thanks,
Ido.
