Question

Does Event and Lock do the same thing in these scenes?

class MyThread1(threading.Thread):
    def __init__(event):
        self.event = event

    def run(self):
        self.event.wait()
        # do something
        self.event.clear()

another:

class MyThread2(threading.Thread):
    def __init__(lock):
        self.lock = lock

    def run(self):
        self.lock.acquire()
        # do something
        self.lock.release()

Answer 1

If you wait on an event, the execution stalls until an event.set() happens

event.wait()  # waits for event.set()

Acquiring a lock only stalls if the lock is already acquired

lock.acquire() # first time: returns true
lock.acquire() # second time: stalls until lock.release()

Both classes have different use cases. This article will help you understand the differences.
