Since the sleep function is a built-in that comes with the Python time module, before using sleep () in Python code, the time should be imported. Adding Python sleep in python programs is essential for programmers in each of such cases and many more. Sometimes, programmers even want to halt their programs between calls of web API, or between queries to a database. Maybe the programmer needs to wait for some file uploads or downloads to complete or for some graphics components to be loaded or drawn on the screen. Sometimes it is required to halt the flow of the program so that several other executions can take place or simply due to the utility required.įor example, a programmer might use this function to simulate a delay in the python program. But do you think of a programmer encountered with a need to make your Python program wait for something? There are some cases a programmer’s best interest would be to make the code sleep in the python program. Most of the programmers want their codes to execute as fast as possible. The sleep () in Python is a handy function that can be used by the developers to halt their python codes for any specified period of time. Example: import threading import time def printproject(). Most of the time you need to create some random delays between iterations in a loop.Python sleep () is one of the most popular functions that come along with the Python module called time. In single-threaded systems, the sleep() method halts the thread and the process as a whole. When the time.sleep command on line 5 is executed I get an error that says Internal error. Here’s an example of how to use time. Python time sleep () function to postpone the calling thread is running, you can refer to the number of seconds by parameter secs, it represents the process. Heres a script I wrote while exploring if then statements. The time module has a function sleep () that you can use to suspend execution of the calling thread for however many seconds you specify. # Sleep a random number of seconds (between 1 and 5) Python has built-in support for putting your program to sleep. Use the following Python’s code snippet to sleep a random number of seconds: To not get banned you can try to add random delays between queries.įor this you can use the Python’s sleep() function that suspends (waits) execution of the current thread for a given number of seconds with the randint() function that returns a random integer.Ĭool Tip: How to set the ‘User-Agent’ HTTP request header in Python!

Basically, the sleep() function, in the Pythons time module is used to suspend or halt the execution of a program for any given number of seconds.
