The interpreter throws a Stop operation and appends the return value to the exception object.

examples

#coroutine code case 1 def simple_coroutine(): print('-> start') x = yield print('-> recived', x) #Main thread sc = simple_coroutine()print(1111)#You can use sc.send(None), the effect is the same next(sc) #Pre-excitation print(2222)sc.send ('zhuxiao ') At this point, the study of "how python delegates generators" is over, hoping to solve everyone's doubts.
