We’ll need to mention the sleep time in the code in order for the program to sleep for a certain number of seconds (or milliseconds).
What is Python Sleep() Function?
We can employ the time to make a Python program sleep for a period. Sleep() is a method that allows the program to sleep. Here, the debate lasts a few seconds. To sleep for milliseconds with this method, simply use a fractional number. To sleep for 400 milliseconds, for example, use time.sleep(0.4), use time for 60 milliseconds sleep(0.06), for example.
Python’s sleep() function is a part of the time package. Python time sleep can be used to delay the execution of a program. You can use the time to pause time or halt the application for a second or millisecond. Sleep() is a function that allows you to achieve this.
Let’s have a look at some examples of the Python sleep function to get a better idea of how it works.
In this first example, we’ll look at how to use the Python sleep() method. This function is part of the time module, we use the dot notation to refer to it, such as time.sleep(). To start, import the time module. We must provide the number of seconds as an argument in order to stop the code from executing.
sec_time = 5
print('sleep time:', str(sec_time), 'seconds')
print('Woke up after', str(sec_time), 'seconds')
Here you can see that when we have executed the code, it shows that the sleep time is 5 seconds as we have specified in the code.
After the 5 second-pause, the rest of the program is executed and printed in the next line.
Because you put your machine on sleep, your program will pause for 5 seconds between the two outputs if you do this.
The time.sleep(secs) method suspends or pauses the execution of the caller thread for the number of seconds specified in the secs parameter. As a result, we must use the time.sleep() method to put the program to sleep for a set period of time. The example code below shows how to use the time.sleep() method to put the program to sleep for the specified amount of time.
print('3 seconds have passed')
The output shows that the program is paused for 3 seconds.
Divide the input by 1000 to have the program halt for milliseconds, as seen in the example code below:
print('200 milliseconds passed')
When 200 milliseconds have passed, the output is shown.
We use Python’s time() module in this method to aid in dealing with time in Python and can be represented as an object, an integer, or even a text. This module also aids in determining the code’s execution speed and efficiency.
If the input time is in milliseconds, we must convert because a second is equivalent to 1000 milliseconds. We multiply the specified number of milliseconds by 0.001 to convert milliseconds to seconds.
It is important to note that the input time was changed and the converted time was recorded in the time_sec variable. With that, we simply used the time.sec variable to invoke the sleep() function to stop the current code from running.
time_in_millisec = 10000
time_sec = 0.001 * time_in_millisec
start_time = time.time()
stop_time = time.time()
time_diff = stop_time - start_time
You’ll receive the following result if you run the code above.
We’re going to use threading in this example. To put the program to sleep for milliseconds, use the Timer() function.
The approach of threads is used to achieve this. In a Python program, a thread is defined as a specific task or code block. A thread is basically a small component of a larger Python program. To deal with various threads more efficiently, Python’s threading module is employed.
The threading module in Python helps with thread creation, management, and control. This module includes a number of objects and functions that can be used to do a range of tasks.
You can make a timer object that will run a function once a definite amount of time has lapsed. The start() method on the timer object is used to start the timer thread (look at the code below.) The message is printed using a function defined in the code. We built a timer object by supplying a milliseconds(ms) sleep time and the function name ‘time_func’ as arguments. The thread started by calling start() on the timer object.
print("This text is printed after 600 milliseconds.")
abc = Timer(0.6 , time_func)
When you run the above piece of code, the following result will be received.
Please notice that we can use the threading module to deal with numerous threads in the same code and specify the execution time for each thread individually. Multithreading is the term for this procedure.
This post was about the sleep() method of Python. If a sleep statement is placed between two statements, the latter will not be performed until the sleep statement’s stated time has passed. The Sleep() function accepts a time value in seconds as an input. However, the input could be in the form of a fraction of a floating point number. So, before passing that number to the function, we must divide it by 1000 to seep for a few milliseconds. We’ve gone through this topic in depth and with a variety of examples in this article.
