A gevent.sleep (0) -     Print("My name is grandson .") -  the  - Gevent.joinall ([ - Gevent.spawn (Zhao), - Gevent.spawn (Qian), + Gevent.spawn (Sun), -])

The example uses gevent to automatically implement IO switching, with the following results:

My surname is Zhao my surname is money my surname is grandchild my name is grandson I call money more my name Zhao Gao process finished with exit code 0

By using the co-process, we can effectively handle multiple concurrency and reduce system overhead.
