>I would really like to know more about python 2.5's new generatorThey're not coroutines. The difference between generators in Python 2.4
characteristics that make them more powerful and analogous to
coroutines. Is it possible for instance to employ them in situations
where I would normally use a thread with a blocking I/O (or socket)
operation? If it is, could someone show me how it can be done? There
appears to be a very limited amount of documentation in this repect,
unfortunately.
and in Python 2.5 is that in Python 2.5, `yield´ can be used as part of
an expression. If a generator is resumed via its `send´ method, then the
`yield´ expression evaluates to the value passed to `send´.
You still can't suspend execution through arbitrary stack frames; `yield´
only suspends the generator it is in, returning control to the frame
immediately above it on the stack.
You can build a trampoline based on generators, but you can do that in
Python 2.4 just as easily as you can do it in Python 2.5.
