sched2 0.8.3

Event scheduler 2

import sched2
sc = sched2.scheduler()

@sc.every(5)
def magic():
    ```python
    print("✨ Magic sparkles every five seconds! ✨")
    ```

sc.run()

The sched2 module extends the general purpose event scheduler sched from Python's standard library. sched2.scheduler is a subclass of sched.scheduler that adds new features such as the every and cron decorators. It's a practical tool for automating tasks that need to run repeatedly after certain time delays or at specific times.

Install

sched2 is available on PyPI.

pip install sched2

How to use

from urllib.request import urlopen
import sched2

# create the scheduler
sc = sched2.scheduler()

# we'll use this to remember the last IP address between runs
last_ip = None


@sc.every(10)  # seconds
def check_ip_address():
    global last_ip  # in case we need to update this

    # get the current IP address
    current_ip = urlopen("https://icanhazip.com/").read().decode("utf-8").strip()

    # if the IP address has changed
    if last_ip != current_ip:
        last_ip = current_ip

        # emit an event to notify the change
        sc.emit("ip_changed", kwargs={"new_ip": current_ip})

@sc.on("ip_changed")  # 'ip_changed' is the event name
def notify_ip_change(new_ip):  # 'new_ip' is the keyword argument passed to the event
    print(f'Your IP address has changed to {new_ip}')

@sc.cron("0 9 * * 1-5")  # every weekday at 9:00
def daily_greeting():
    print(f'Good morning, your current IP address is {last_ip}')

sc.run()
