threading.Event()

threading.Event() is a Python function in the Threading Module category. Creates an event object for inter-thread communication. Threads can wait for an event to be set. The syntax is threading.Event(). Returns: Event object. A typical example: event = threading.Event() # In thread A: event.wait() # In thread B: event.set() # Signal thread A. A close sibling is threading.Thread(), which creates a new thread object that runs the target function with args. A close sibling is thread.Thread.start(), which starts the thread activity. Must be called at most once per thread. A close sibling is thread.Thread.join(), which waits for the thread to terminate. Blocks until timeout or completion. A close sibling is threading.Lock(), which creates a new primitive lock (mutex). Only one thread can acquire the lock at a time.
