为什么我收到 AttributeError: Object has no attribute [英] Why am I getting AttributeError: Object has no attribute

问题描述

我有一个类 MyThread.我有一个方法示例.我试图从同一个对象上下文中运行它.请看代码:

I have a class MyThread. In that I have a method sample. I am trying to run it from within the same object context. Please have a look at the code:

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，我收到此错误

Looks very simple ain't it. But when I run it I get this error

AttributeError: 'myThread' object has no attribute 'sample' 现在我有了那个方法，就在那里.那么怎么了?请帮忙

AttributeError: 'myThread' object has no attribute 'sample' Now I have that method, right there. So what's wrong? Please help

这是堆栈跟踪

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

我是这样称呼的

arThreads = []
maxThreads = 2;

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

抱歉，我不能发布 redisOps 类代码.但我可以向你保证它工作得很好

Sorry I can't post redisOps class code. But I can assure you that it works just fine

推荐答案

您的缩进是错误的，并且混用了制表符和空格.使用 python -tt 运行脚本进行验证.

Your indentation is goofed, and you've mixed tabs and spaces. Run the script with python -tt to verify.
