Python Timer Usage Guide

In Python, the Timer is a thread class used to execute a function after a specified time. The usage of the Timer class is as follows:

1. Firstly, we need to import the Timer class.

from threading import Timer

1. Create a Timer object and specify a delay time and the function to be executed.

def my_function():
    print("Timer is up!")

# 创建一个延迟5秒后执行my_function函数的Timer对象
t = Timer(5, my_function)

1. Start the Timer object.

t.start()

In the example above, a Timer object was created to execute the my_function function after a delay of 5 seconds, and the object was started. When the timer reaches the specified time, the my_function function is executed and the message “Timer is up!” is displayed.

It’s important to note that the Timer object runs on a separate thread. After starting the Timer object, the program will continue executing the code below while the Timer object will run on another thread to time and execute the specified function.
