好的，首先检查以下代码：class DemoClass(): def __init__(self): #### 我真的想知道 self.Counter 是否是线程安全的。 self.Counter = 0 def Increase(self): ...

好的，首先检查以下代码：

class DemoClass():

    def __init__(self):
        #### I really want to know if self.Counter is thread-safe. 
        self.Counter = 0

    def Increase(self):
        self.Counter = self.Counter + 1

    def Decrease(self):
        self.Counter = self.Counter - 1

    def DoThis(self):
        while True:
            Do something

            if A happens:
                self.Increase()
            else:
                self.Decrease()

            time.sleep(randomSecs)

    def DoThat(self):
        while True:
            Do other things

            if B happens:
                self.Increase()
            else:
                self.Decrease()

            time.sleep(randomSecs)

    def ThreadSafeOrNot(self):
        InterestingThreadA = threading.Thread(target = self.DoThis, args = ())
        InterestingThreadA.start()

        InterestingThreadB = threading.Thread(target = self.DoThat, args = ())
        InterestingThreadB.start()

我遇到了与上述相同的情况。我真的想知道它是否是线程安全的 self.Counter ，如果不是，我有什么选择？我只能想到 threading.RLock() 锁定此资源，有什么更好的主意吗？
