我有一堂MyThread。在那，我有一个方法示例。我试图从同一个对象上下文中运行它。请看一下代码:

class myThread (threading.Thread):
    def __init__(self, threadID, name, counter, redisOpsObj):
        threading.Thread.__init__(self)
        self.threadID = threadID
        self.name = name
        self.counter = counter
        self.redisOpsObj = redisOpsObj
        
    def stop(self):
        self.kill_received = True
            
    def sample(self):
        print "Hello"
                
    def run(self):
        time.sleep(0.1)
        print "\n Starting " + self.name
        self.sample()

看起来很简单是不是。但是当我运行它时，我得到了这个错误AttributeError: 'myThread' object has no attribute 'sample'现在我有了那个方法，就在那里。那么有什么问题呢？请帮忙
编辑:这是堆栈跟踪

我这样称呼它

arThreads = []
maxThreads = 2;

for i in range( maxThreads ):
    redisOpsObj = redisOps()
    arThreads.append( myThread(i, "Thread-"+str(i), 10, redisOpsObj) )

抱歉，我无法发布 redisOps 类代码。但我可以向你保证，它工作得很好

您的缩进是错误的，并且您混合了制表符和空格。使用 python -tt 运行脚本验证。
