It seems that there are API access restrictions per unit time of Twitter, so if there are too many, an exception will be thrown on the way. Avoid by putting sleep in the middle. With this, the user at the moment when the exception is thrown can not be surely followed, but well, it is not such a critical code, is it okay?

If you change it a little, you can use it in the opposite way.
