How to use the "Schedule" class library in Python for parallel task scheduling

Use the "Schedule" class library to schedule in parallel mission in Python Overview: In many applications, we need to perform some tasks regularly.However, in some cases, these tasks may take a long time, causing the entire program to be blocked.To solve this problem, you can use parallel task scheduling to perform regularly without affecting the operation of the main program.The "Schedule" class library in Python provides a simple way to perform parallel task scheduling. step: 1. First, make sure that the "Schedule" class library has been installed.You can use the following command to install it: pip install schedule 2. Import the "schedule 'class library and other required libraries, such as' time' and 'threading' (for parallel execution): python import schedule import time import threading 3. Define tasks to be executed regularly.In the following example, we will create a simple function that prints the current time every 5 seconds: python def my_task(): Print ("Current Time:", Time.ctime ()) 4. Set the scheduling timetable of the task.In the following example, we will perform a task every 5 seconds: python schedule.every(5).seconds.do(my_task) 5. Create a function to perform the scheduling task: python def run_schedule(): while True: schedule.run_pending() time.sleep(1) 6. Start the thread to perform the task scheduling parallel: python t = threading.Thread(target=run_schedule) t.start() 7. Finally, let the main program continue to perform other operations, and the task will be performed regularly in the background. Complete code example: python import schedule import time import threading def my_task(): Print ("Current Time:", Time.ctime ()) schedule.every(5).seconds.do(my_task) def run_schedule(): while True: schedule.run_pending() time.sleep(1) t = threading.Thread(target=run_schedule) t.start() while True: # The main program continues to perform other operations pass The code in this example will create a background thread that uses the "Schedule" class library to perform regular tasks.You can adjust the scheduling frequency of the task according to your needs and the operation to be performed in the task.Note that add an infinite loop (such as `While True`) to the main program so that the task scheduling thread can run in the background. Summarize: Using the "Schedule" class library can easily achieve parallel task scheduling to avoid long -term tasks to block the operation of the entire program.You can set the scheduling frequency and execution operation according to your needs.Remember, add an unlimited cycle to the main program to ensure that the task scheduling thread has been running in the background.
