在 python 中终止线程的最佳方法是什么？

Question

I am implementing a Flask application and I'm calling a function A, based on a request. Inside the function A, there is another function called B and it is called. But, I don't need to wait until the end of the execution of function B to return the output from function A. I have done it with the following code implementation.

from threading import Thread

def functionA():
    result = doSomething1()
    Thread(target=functionB).start()
    return result

def functionB():
    # Do something after the execution of doSomething1()

Here, I am starting a new thread and do what I need to do but, I do not terminate the newly started thread. Do I need to terminate that thread by myself? If so, what is the best way to do that?

Answer 1

A thread will terminate on its own. To see if it is alive you can use thread.is_Alive()

If you must force termination of a thread, use thread.join() would be the closes option, as this blocks the calling thread until the thread in question has finished.
