详解Python如何轻松实现定时执行任务

import schedule
import time
import papermill as pmdef job():
    pm.execute_notebook(
       'input.ipynb',
        'logs/oo.ipynb'
    )
schedule.every(10).seconds.do(job)
while True:
    schedule.run_pending()
    time.sleep(1)

pip install schedule papermill ipywidgets

import schedule
import time

# 要执行的任务
def job():
    print("I'm working...")

#每隔10s执行job
schedule.every(10).seconds.do(job)
#每隔10分钟执行job
schedule.every(10).minutes.do(job)
#每小时执行job
schedule.every().hour.do(job)
#在每天10:30分执行job
schedule.every().day.at("10:30").do(job)
#每5到10分钟（随机数）执行job
schedule.every(5).to(10).minutes.do(job)
#每星期一执行job
schedule.every().monday.do(job)
#每星期三13:15执行job
schedule.every().wednesday.at("13:15").do(job)
#每天欧洲阿姆斯特丹时区的12:42执行job
schedule.every().day.at("12:42", "Europe/Amsterdam").do(job)
#在每分钟的第17秒开始执行job
schedule.every().minute.at(":17").do(job)

def job_with_argument(name):
    print(f"I am {name}")
#每10秒钟执行一次job_with_argument（带参数）
schedule.every(10).seconds.do(job_with_argument, name="Peter")

while True:
    schedule.run_pending()
    time.sleep(1)
