为什么我收到 AttributeError: 对象没有属性？ [关闭]

我有一个类 MyThread。其中，我有一个方法示例。我正在尝试从同一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()

看起来很简单不是吗。但是当我运行它时我收到此错误

AttributeError: 'myThread' object has no attribute 'sample'现在我有了这个方法，就在那里。那么出了什么问题呢？请帮忙

编辑：这是堆栈跟踪

Starting Thread-0

File "./redisQueueProcessor.py", line 51, in run

AttributeError: 'myThread' object has no attribute 'sample'

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

你的缩进是错误的，并且你混合了制表符和空格。运行脚本python -tt核实。
