![]() ![]() It may decide to let the thread block for a little longer before waking it up and allowing it to resume execution (e.g. This is because the underlying operating system decides what threads should run and when to run them. … the suspension time may be longer than requested by an arbitrary amount because of the scheduling of other activity in the system. The calling thread will block for at least the specified number of seconds, but may block for longer. This may happen if the user presses Ctrl-C to send a SIGINT (signal interrupt) to the process that owns the thread, which by default will terminate the process. The actual suspension time may be less than that requested because any caught signal will terminate the sleep() following execution of that signal’s catching routine. ![]() The calling thread may block for less than the time specified, if the process is interrupted. We may also call the time.sleep() function from a new thread used to execute a custom function. We may call the time.sleep() function from the main thread, which is the default thread in your progress. In concurrent programming we may want the current thread to block or sleep for a specified time. Threading in Python: The Complete Guide.You can learn more about Python threads in the guide: Python provides the ability to create and manage new threads via the threading module and the threading.Thread class. Sometimes we may need to create additional threads in our program in order to execute code concurrently. Both processes and threads are created and managed by the underlying operating system. time.A thread is a thread of execution in a computer program.Įvery Python program has at least one thread of execution called the main thread.To show that things were paused for the correct duration, the result of the time.ctime() method was printed before and after time.sleep().The time module must be imported first using import time.time.sleep(seconds) will pause execution for the given number of seconds.If you want to wait for a specified duration or number of seconds, you can use the sleep function from Python’s time module. Pausing for a Duration of Time using the time.sleep() Method As the result of input()* isn’t assigned to a variable, it’s discarded.However, we’re using it to wait as it will only complete executing once the ENTER key is pressed, allowing the code following it to continue.input() will accept any input and is usually used for accepting user input to a variable.The code will run, wait for the user to press ENTER, and then continue running – in this case, it’s just printing text before and after the wait.Print("More very important program output") This code snippet will wait until the user presses the enter Key. Pausing a Python Program by Waiting for User Input Python can be used to make useful command-line tools to streamline your workflow, but sometimes you need to wait for the user, or for a pre-defined amount of time.įor example, you may want to prompt the user to press a key when they have finished reading instructions or give them time to override a default action. It’s part of the ‘time’ module and allows you to pause, sleep, wait, or stop a Python script or application. There is a useful function in Python called ‘ sleep()’. ![]()
