新线程中的Python对象方法

Question

I have an object instantiated in the main thread and i wish to run one of it's methods in a different thread asynchronously . Here is the code i used:

obj = self._collection[index]
t1 = threading.Thread( target = obj.foo() )
t1.start()

The method does execute but it is in sync with the main thread.

Answer 1

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.
