Create a thread using a class constructor as function

Question

I know that I can create and start a thread in Python using the following syntax:

import threading

tracker_thread = threading.Thread(target=func, args=(x,y,z))
tracker_thread.daemon = True
tracker_thread.start()

What I need is to use a class constructor as target. I know that a solution for this is the following:

def wrap_function(x,y,z):
    MyClas(x,y,z)

tracker_thread = threading.Thread(target=wrap_function, args=(x,y,z))

But I am trying to avoid the use of a similar "wrap function", by using only the constructor in the initialization of Thread.

How can I do this?

threading.Thread(target=MyClass, args=(x, y, z)) didn't work? — sirfz

Solved. The simplest solution is always the best:

tracker_thread = threading.Thread(target=MyClass, args=(x,y,z))

Thanks to Sir_FZ for the comment.

is it args=[x, y, z] or args=(x, y, z)?

Yeah -- Python "no special syntax for instantiating objects" wins again! The only time function/class interchange ever got me is in writing a decorator as a class, and use it to decorate a method in Python 3. (hint: you decorator will need a __get__ method)
