Nov 19, 2020 Use time.sleep to set the delay You can set a delay in your Python script by passing the number of seconds you want to delay to the sleep function: time.sleep(5) This means you want the script to delay 5 seconds before continuing. Description The method sleep suspends execution for the given number of seconds. The argument may be a floating point number to indicate a more precise sleep time. 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.
To make a Python program delay (pause execution), use the sleep(seconds) method. which can be found in the time module.
The time module provides many time related functionality like getting the current time, converting epoch time and others.

The time.sleep pauses execution, making the program wait for the defined time. The time to wait (sleep) is defined in seconds. If you don’t want the program to completely freeze use threading instead.
The time.sleep(sec) method supports floating point numbers, meaning you can make it wait half a second too
A simple countdown timer from 5:
The time.sleep(seconds) is not real time. The accuracy depends on the operating system, sometimes it may be off in terms of milliseconds.
To wait about 50 milliseconds:
You won’t get exactly 50ms if you rely on the sleep method.
Most PC machines have hardware limits in the 1-10ms range, regardless of operating system. To the operating system, time.sleep() just means a hint. It’s not a good timing mechanism, but good enough for most applications.

Operating systems may have different implementations, causing a difference in time.

For higher accuracy, you need dedicated hardware (embedded system) to keep accurate time on the milliseconds level.
