multithreading - The Programming Theory Gods Strike: What is target = foo in Python 2.x? -

often have been browsing q & site, answers use multi-threading , processing have told me use format goes this:

(target=foo, args=(bar, baz)) 

it used in multiprocessing , multithreading (at least limited knowledge.)

my question is, what target mean, , can explain how used?

i have not been able find explanation in docs or elsewhere.

the keyword argument target in threading.thread's constructor sets entry-point of new thread. can function or object has __call__ method.

here's example using function:

import threading  def foo(number, name):     print 'hello new thread'     print 'here arguments:', number, name  thread = threading.thread(target=foo, args=(5,'bar')) thread.start()  thread.join()
