Note that in Linux, you can install the RT_PREEMPT patch set, which allows you to have a semi-realtime kernel. There are two more Python modules that help you deal with time and date: calendar handles the calendar-related functions, and datetime lets you manipulate Python timestamps. The sleep() work suspends the execution of the current string for a given number of seconds. The sched module defines a class which implements a general purpose event scheduler:. In order to use this method to sleep for milliseconds, you just use a fractional number. Here’s an example of how to use time.sleep (): >>>. Using Python time.sleep() on a Thread.
