I\'m familiar with yield to return a value thanks mostly to this question

but what does yield do when it is on the right side of an assignment?

Answer 1

You can send values to the generator using the send function.

If you execute:

p = protocol()
p.next() # advance to the yield statement, otherwise I can't call send
p.send(5)

then yield will return 5, so inside the generator c will be 5.

Also, if you call p.next(), yield will return None.
