On the other hand, the random randint method can be used together with the sleep function as with random randint you will be able to generate a random number given a specified range so that the sleep function will be stopped for a different period of time for each request which is made. Basically, with sleep you can make the script stop for a certain period of time so that if you are making some requests iteratively you can avoid the server to be overloaded. The sleep function can help you to avoid the server to be overloaded with too many requests in a very short period of time.
