This corresponds to the .NET ManualResetEvent and is used to collaborate among multiple threads. Event.wait () waits for the event signal to continue execution, set () sets the signal so that the waiting thread can execute, and clear () clears the signal.

Event1 = Event () event2 = Event () def test1 (): for i in range (5): event1.wait ()

Wait for the signal

Print currentThread () .name, I event1.clear ()

When the execution is complete, clear the flag (flag) so that the next time you wait (), you need to wait for notification again.

Event2.set ()

Set another wait event to signal another thread.

Def test2 (): for i in range (5): event2.wait () print currentThread (). Name, I event2.clear () event1.set () Thread (target = test1). Start () Thread (target = test2). Start () event1.set ()

Remember to activate one first, or they'll all be there waiting to die. Output:
