This depends on your code logic. But from the code supplied, most probably it is Timer from threading module, so you just have to add this at the top of your code

from threading import Timer

Documentation is here: threading.Timer

One advantage of using the @contextmanager decorator to define our timer is that we can use the timer both using the with statement and as a function decorator, like in the last example. If we wanted to time a certain operation once, we could call in timer() using a with statement.

time — Time access and conversions
On Windows, if secs is zero, the thread relinquishes the remainder of its time slice to any other thread that is ready to run. If there are no other threads ready to run, the function returns immediately, and the thread continues execution. On Windows 10 and newer the implementation uses a high-resolution timer which provides resolution of 100 nanoseconds.

August 8, 2024 - In this blog post we will investigate how we implement a timer to add in any of our Python game/projects. To do so we will use the time library in Python. So, to import the time library we will add the following line of code at the top of our code: [enlighter lang="python" offset=0]import time[/enlighter]

November 10, 2021 - Not much going on here, we just import the time library ( which should be part of your default python install ) and call a few methods:time.strftime To get and format the current timetime.sleep(1) This just tells your script to wait one second before looping back at the while level.You should get a readout in your terminal like:14:39:43 14:39:44 14:39:45 14:39:46 14:39:47 14:39:48 14:39:49To exit the loop just hit Ctrl + C
