If you don’t know what a System Call is, then you should! Well, it is, but it is simply a wrapper around something else that is implemented by the Operating System.Īll Operating Systems have a Sleep() system call. Sleep is not actually implemented by Python. If what you are trying to do is to block a thread until a condition happens, it is much better to use wait(). The straight-forward way is to precompute the delay (in seconds) until that specific time before you call the sleep function.Īnother way is to use the event.wait function from the event module.

Time.sleep(1 * 10**(-6)) Q: How to use the sleep function to sleep until a specific time?ĭepending on what you are trying to do, there are two different ways to achieve this. The sleep function actually takes a floating point number as an argument, not an integer.Īnd that means, you can pass any fraction of a second as an argument. Frequently Asked Questions Q: How to use the sleep function to sleep for a time period that is less than a second, for example milliseconds or microseconds? You can use the sleep function in Python 2 exactly as you do in Python 2. import timeĪs you can see, the elapsed time is very close to 10 seconds which is what we expect. In the following example, I print out the elapsed time between invoking the sleep function and after it returns. Let’s say you want to use sleep to add a 10-second delay. It is really very simple and straight-forward.

Using the sleep function in Python 2 and Python 3 is exactly the same, so you won’t need to worry about which version of Python your code is running on. Sleep takes only one argument which is the period of time in seconds that you want to sleep for. So in order to use sleep, you will need to import the time module first. Like I mentioned, Sleep is a Python built-in function in the time module. After that I will talk more about some frequently asked questions and how the sleep function is actually implemented under the hood. If this is what you want to do, then you should use the sleep function from the time module.įirst, I will start by discussing how to use Python’s sleep function. In Python, or any other programming language, sometimes you want to add a time delay in your code before you proceed to the next section of the code.
