3 cards from this section. Quick, good the night before a test.
What does event.set() do?
Think of it as sending a green light to waiting threads.
What method do you use to wait for an event?
This is like standing by until someone tells you it's time to go.
What method is used to block a thread until an event is set?
Think about what it means to wait for a signal before proceeding.
True or False: An Event can be used for signaling between multiple threads.
Recall that Events are intended for communication in concurrent programming.
Create a Python program that uses two threads communicating via an Event. One thread should produce data that the other thread consumes ignoring race conditions.
Think about how to ensure the consumer waits until the producer has finished filling the data.
What are the potential pitfalls of using Events for synchronization? Discuss in terms of deadlocks or race conditions.
Consider how forgetting to set an event might leave waiting threads stuck.
