如何以编程方式创建新的cron作业？

pip install croniter

from croniter import croniter
import datetime

def create_cron_job(cron_expression, job_func):
    current_time = datetime.datetime.now()
    cron = croniter(cron_expression, current_time)
    next_time = cron.get_next_datetime()
    
    while True:
        if datetime.datetime.now() >= next_time:
            job_func()
            next_time = cron.get_next_datetime()

# 示例作业函数
def my_job():
    print("执行作业...")

# 创建新的cron作业
create_cron_job("*/5 * * * *", my_job)
