Cancelling previous schedule

[cosmarchy]

Hi,

Just starting out with Python and am using VSCode to schedule a simple task so am using the following to get started:

import sched
import time

s = sched.scheduler(time.time, time.sleep)
def do_something(sc): 
    print("Doing stuff...")
    # do your stuff
    s.enter(2, 1, do_something, (sc,))

s.enter(2, 1, do_something, (s,))
s.run()

This runs ok and I get "Doing stuff" printed in the terminal but I was struggling to see what the units were - I can see that it was run after 2 somethings (seconds I believe) but I couldn't see from any documentation I could find how you might change this to days or hours etc, so I went looking for some other code and came up across this:

import schedule
import time

def job():
   print("I'm working...")

schedule.canceljob
schedule.every(10).seconds.do(job)

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

Again this looks like what I need but I cannot run as whenever I do, I get "Doing stuff" printed in the terminal, instead of "I'm working..." which is what I'd expect and leaves me to believe there is something of the previous code still running despite cancelling with ctrl-c. Both of these code examples are in separate files and the one which isn't being worked on is closed.

Is there something going on in the background with schedule which is not being closed down? If so, how can you close off previous jobs when the code exits???

Thanks

Yes you have to use Ctrl+c to shut it down.
Your second code with schedule is line 7 wrong.
Code will not run with that error,look at Cancel a job doc
So a example run.

import schedule
import time

def job():
   print("I'm working...")

schedule.every(10).seconds.do(job)
while 1:
   schedule.run_pending()
   time.sleep(1)

Output:
G:\div_code\answer
λ python 10_sec.py
I'm working...
I'm working...
I'm working...
I'm working...
Traceback (most recent call last):
  File "G:\div_code\answer\10_sec.py", line 10, in <module>
    time.sleep(1)
KeyboardInterrupt
^C

In background there will a process python.exe(python on Linux) running which has a own pid.
If want to see processes in background eg shut down from Python look at psutil.

Here's something I wrote back in 2016 which may be of interest: https://python-forum.io/thread-1304.html
a timer can be set to wait days, hours, minutes, and/or seconds, for simultaneous projects.
