Generating Random Numbers with APScheduler#s ThreadPoolExecutor and BackgroundScheduler

This code defines a function named random_task that uses APScheduler's ThreadPoolExecutor and BackgroundScheduler to generate and print a random number every 10 seconds.

Technology Stack : APScheduler, ThreadPoolExecutor, ProcessPoolExecutor, BackgroundScheduler, random

Code Type : Timed task

Code Difficulty : Intermediate

                
                    
from apscheduler.executors.pool import ThreadPoolExecutor, ProcessPoolExecutor
from apscheduler.schedulers.background import BackgroundScheduler

def random_task():
    # This function demonstrates the use of ThreadPoolExecutor and BackgroundScheduler from APScheduler.
    def generate_random_number():
        import random
        return random.randint(1, 100)

    with ThreadPoolExecutor(max_workers=5) as executor:
        result = executor.submit(generate_random_number)
        print(f"Random number generated: {result.get()}")

# Scheduler configuration
scheduler = BackgroundScheduler()

# Schedule the random_task function to run every 10 seconds
scheduler.add_job(random_task, 'interval', seconds=10)

# Start the scheduler
scheduler.start()

# To keep the main thread alive
try:
    while True:
        time.sleep(2)
except (KeyboardInterrupt, SystemExit):
    scheduler.shutdown()
