tornado equivalent of delay

Question

Is there an equivalent command in tornado for delay function without affecting the main process to sleep (thus the callbacks would execute even when the main thread is dealy

Answer 1

Note that since 4.1 they've added a gen.sleep(delay) method.

so

yield gen.Task(IOLoop.instance().add_timeout, time.time() + 5)

would just become

yield gen.sleep(5)
