Question

I am using threading.py and I have the following code:

import threading  
class MyClass(threading.Thread):  
    def __init__(self,par1,par2):
       threading.Thread.__init__(self)  
       self.var1 = par1  
       self.var2 = par2  
    def run(self):
       #do stuff with var1 and var2 while conditions are met
... 
... 
... 
myClassVar = MyClass("something",0.0)

And I get the following error:

18:48:08    57  S E myClassVar = MyClass("something",0.0)  
18:48:08    58  S E File "C:\Python24\Lib\threading.py", line 378, in `__init__`  
18:48:08    59  S E assert group is None, "group argument must be None for now"  
18:48:08    60  S E AssertionError: group argument must be None for now  

I am kind of new using python, it is the first time I use threading…

What is the bug here?

Thank you,

Jonathan

You don’t have to extend Thread to use threads. I usually use this pattern…

def worker(par1, par2):
    pass # do something

thread = threading.Thread(target=worker, args=("something", 0.0))
thread.start()
