python - 类型错误 : the first argument must be callable in scheduler library

Question

运行调度程序库时出现以下错误。我确实经历过类似的问题和答案，但不知何故无法识别导致错误的根源。有人可以帮我解决我出错的地方吗？

TypeError: the first argument must be callable

import schedule
    import time


class Scheduler():

    def trigger_testsuite(self):
        print("I am working as expected.")

    def scheule_a_job(self, type="Secs", interval=5):

        if (type == "Mins"):
            schedule.every(interval).minutes.do(self.trigger_testsuite())

        if (type == "Secs"):
            schedule.every(interval).seconds.do(self.trigger_testsuite())

        if (interval == "Hrs"):
            schedule.every().hour.do(self.trigger_testsuite())

        if (interval == "Daily"):
            schedule.every().day.at("10:00").do(self.trigger_testsuite())

        while True:
            schedule.run_pending()
            time.sleep(1)


if __name__ == "__main__":
    run = Scheduler()
    run.scheule_a_job()

回溯:-

I am working as expected.
Traceback (most recent call last):
  File "foo/Scheduler.py", line 31, in <module>
    run.scheule_a_job()
  File "foo/Scheduler.py", line 16, in scheule_a_job
    schedule.every(interval).seconds.do(self.trigger_testsuite())
  File "foo\Python\Python38-32\lib\site-packages\schedule\__init__.py", line 440, in do
    self.job_func = functools.partial(job_func, *args, **kwargs)
TypeError: the first argument must be callable

不要在传递给的函数中包含括号:

schedule.every(interval).minutes.do()

所以，这一行:

schedule.every(interval).minutes.do(self.trigger_testsuite())

应该是:

schedule.every(interval).minutes.do(self.trigger_testsuite)

其他人也一样。最终代码变为:

import schedule
    import time


class Scheduler():

    def trigger_testsuite(self):
        print("I am working as expected.")

    def scheule_a_job(self, type="Secs", interval=5):

        if (type == "Mins"):
            schedule.every(interval).minutes.do(self.trigger_testsuite)

        if (type == "Secs"):
            schedule.every(interval).seconds.do(self.trigger_testsuite)

        if (interval == "Hrs"):
            schedule.every().hour.do(self.trigger_testsuite)

        if (interval == "Daily"):
            schedule.every().day.at("10:00").do(self.trigger_testsuite)

        while True:
            schedule.run_pending()
            time.sleep(1)


if __name__ == "__main__":
    run = Scheduler()
    run.scheule_a_job()
