Python多线程问题 请大虾们帮忙看看~~谢谢了? 400 报错
我用的平台是PythonWin,版本是3.3。 当输入t = Mythread(2) 生成Mythread对象时,就出错了,现在还没有头绪,望指教! >>> import threading >>> import time >>> class Mythread(threading.Thread): ... def init(self,id): ... threading.Thread.init(self) ... self.id = id ... def run(self): ... x = 0 ... time.sleep(60) ... print (self.id) ... >>> def func(): ... t.start() ... for i in range(5): ... print (i) ... >>> t = Mythread(2) Traceback (most recent call last): File "<interactive input>", line 1, in <module> File "E:\Program Files (x86)\Python33\lib\threading.py", line 536, in init assert group is None, "group argument must be None for now" AssertionError: group argument must be None for now >>> File "<interactive input>", line 1, in <module> File "E:\Program Files (x86)\Python33\lib\threading.py", line 536, in init assert group is None, "group argument must be None for now" AssertionError: group argument must be None for now |

试试 t=Mythread(None)
