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.
sched2
is available on PyPI.
pip install sched2
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}')
