python问题，threading多线程如何实现

Question

主要代码如下，执行后，here会打印3次，但是 timer对应的函数只调用了1次，请问是什么情况

            names = locals()
            thread_list = []
            for thread_i in range(3):
                names['th'+str(thread_i )] = threading.Thread(target=self.timer.start(500))
                thread_list .append(names['th'+str(thread_i )])
                names['th'+str(thread_i )].start()
                print("here")

Answer 1

我都看不到你调用timer的代码
代码不全面，不好看问题

现在是想，点一下pushButton_kafka_producer_text_send按钮，能并发执行timer对应的函数
