python - thread`s target is a method of an object

To fix the issue you can do The target should be a function, not a function call, so use this instead:
target=producer.generateItem    

t1 = threading.Thread(target = producer.generateItem, name = "thread1")
t2 = threading.Thread(target = consumer.consumeItem, name = "thread2", args = (1))

# function names without parenthesis

what can happen if some thread makes object null and other thread is inside method of that object

like below fixes the issue Summarising SJuan76 and the op's discussion:
Looks like there are two references to t, but only one to b (the one inside t). t will not get released, because the threads hold it independently. However, b may be deleted (depending on gc) because its ref count will drop to zero once the reference is nullified.

Python object method in a new thread

Hope this helps Use t1 = threading.Thread( target = obj.foo ) instead.
In this case, the Thread constructor is expecting a reference to a function...when you pass it obj.foo(), you are passing it the result of the foo() function. That's not what you want! Pass a reference to the function.

Get target Object in Aspect and call another method on target object

this will help I figured out how to invoke the method. I need to get the method and invoke it, then I do not need to do casting for the class.

Object targetObject  = joinPoint.getTarget();
Method m = targetObject.getMethod("getC");
m.invoke(targetObject);

What happens to a thread executing a method as target

I think the issue was by ths following , A simple test shows that the thread is still in memory, "stopped" after it finishes its process:
import threading

def speak():
    pass

thread = threading.Thread(target=speak, args=())
thread.start()
thread.join() # wait for the process to finish;

print thread

# Result: <Thread(Thread-1, stopped 21864)>
