Use the "Schedule 'class library in Python to achieve cyclical task scheduling

Use the "Schedule 'class library in Python to achieve cyclical task scheduling In daily programming, we sometimes need to perform some tasks periodic.To achieve this goal, you can use the 'Schedule' library in Python.The library provides a simple and flexible way to schedule and perform tasks. First, we need to install the 'Schedule' library.You can install the following commands in the terminal: python pip install schedule After the installation is completed, we can start writing code. First, introduce the time module of the 'SCHEDULE' library and related time modules: python import schedule import time Next, we can define a function, which is the task we need to execute cyclical.For example, we can define a function to print the current time: python def print_time(): Print ("Current Time:", Time.Strftime ("%Y-%M-%D%H:%S", Time.localtime ()) We can then use the related functions of the 'Schedule' library to schedule the task.For example, we can use `Schedule.every (1). Minutes.do (Print_time)` means the task of executing the print time every one minute.You can adjust the time interval as needed. Next, we need to constantly check whether the task needs to be executed.We can use an unlimited cycle to implement this function.In the cycle, we can use `schedule.run_pending ()` to check the task and perform tasks that need to be executed.At the same time, use the `Time.sleep (1)` to ensure that the time difference between each cycle will be too long. The following is a complete code example: python import schedule import time def print_time(): Print ("Current Time:", Time.Strftime ("%Y-%M-%D%H:%S", Time.localtime ()) schedule.every(1).minutes.do(print_time) while True: schedule.run_pending() time.sleep(1) In the above example, every 1 minute, the program will print the current time.You can modify the task and time interval according to your needs. It is worth noting that the program will continue to run until manual stop.Therefore, if you need to stop the task scheduling at a certain point in time, you can consider setting the corresponding stop conditions or capturing interrupt signals in the code. In this way, we can use the 'schedule' library in Python to achieve cyclical task scheduling.Regardless of whether the task is executed regularly or according to a certain time interval, the library provides a lot of flexible options to facilitate us to deal with various task scheduling requirements.
