I would normally define the version, such as in the second example. It's just that for these quick and dirty code fragments, I grabbed examples off the internet and simply ran them to see what would happen; forgetting the shebang. > What was the third?

I tried syntax checking the code in Idle 3, but there is no apscheduler module for Python 3, so all I got was the 'no module' error. > python -c 'f = "foo.py"; compile(open(f).read(), f, "exec")' > > And for something to check the semantics, there's > > $ pylint -E foo.py > No config file found, using default configuration > * Module foo > E: 1, 0: Undefined variable 'os' (undefined-variable) > $ > > This kind of thing can be part of your `check' target in your > ./makefile. :-) I will be compiling the finished item so that I can run it efficiently in piCore on the Pi Zero, but I never thought of compiling it to check the error. Thanks for your help.

Where should I expect the logger to write its output? Answering myself; it wrote to the shell :-) The problem was that I'd forgotten to import os ;-) -- Terry Coles -- Next meeting: Bournemouth, Tuesday, 2016-09-06 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR
Re: [Dorset] Can anyone help with using apscheduler in Python?
Hi Terry, > No handlers could be found for logger "apscheduler.scheduler" It's handy for Python questions to state whether it's 2 or 3. :-) Running Python in the same method as your script with its --version option will say. Add `import logging' to your other imports, and then immediately after try `logging.basicConfig()'. Cheers, Ralph. -- Next meeting: Bournemouth, Tuesday, 2016-09-06 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR
[Dorset] Can anyone help with using apscheduler in Python?
Hi,
Most of you are aware by now that Clive and I have a project to bring the
bells back to the Wimborne Model Town Minster. I've been experimenting with
using apscheduler and mpg321 in Python to realise this. It's pretty crude at
the moment, but if I run two separate programs (the bells and the schedule)
both parts work.
Taking mpg321 first; this code works perfectly:
#!/usr/bin/env python
from time import sleep
import os, random
try:
while True:
os.system('mpg321 -g 100 -q ./mp3/amersham.mp3')
sleep(1);
os.system('mpg321 -g 100 -q ./mp3/nottingham_smv.mp3')
sleep(1);
os.system('mpg321 -g 20 -q ./mp3/peterboro.mp3')
sleep(1);
finally:
sleep(1)
Also, here is a fragment of my (separate) scheduling program, without the
bells:
#!/usr/bin/env python2.7
import datetime
import time
from apscheduler.scheduler import Scheduler
# Start the scheduler
sched = Scheduler()
sched.daemonic = False
sched.start()
def one_oclock():
print("One O'clock")
print(datetime.datetime.now())
time.sleep(1)
# Schedule functions to be run
sched.add_cron_job(one_oclock, hour='1')
So far so good. However, when I combine the two and add the system call to
mpg321 after the sleep into my functions, eg:
def one_oclock():
print("One O'clock")
print(datetime.datetime.now())
time.sleep(120)
os.system('mpg321 -g 20 -q ./mp3/Wedding_March.mp3')
time.sleep(300)
os.system('mpg321 -g 100 -q ./mp3/amersham.mp3')
I get:
Python 2.7.12 (default, Jul 1 2016, 15:12:24)
[GCC 5.4.0 20160609] on linux2
Type "copyright", "credits" or "license()" for more information.

No handlers could be found for logger "apscheduler.scheduler"
The debugger doesn't really help, so how can I find out what I'm doing wrong?
