Python多线程报错之RuntimeError

写多线程脚本，运行的时候报错
File “/usr/local/lib/python2.6/threading.py”, line 465, in start
raise RuntimeError(“thread.init() not called”)
RuntimeError: thread.init() not called
原因是线程类中构造函数init()中未调用父类的初始化方法，在init()函数里加入调用父类初始化方法的代码就OK了，
类似下边这样　threading.Thread.init(self)

class MyThread(threading.Thread):
    def __init__(self,ip_port_seg):
        threading.Thread.__init__(self)
        self.ip_port_seg = ip_port_seg
