Is there a Python function that checks if a generator is started?

Question

I try to define a generator function mycount() that can be reset with the generator function send(0) as in the example below. Everything works fine

Answer 1

In particular, you might find a way to use the consumer decorator described on p. I-131 of David Beazley's "Generator Tricks," to which J. Gwyn provided a link:

def consumer(func):
    def start(*args,**kwargs):
        c = func(*args,**kwargs)
        c.next()
        return c
    return start

I use something similar in my code.

Note that if v is None is preferred over if v == None.
