Why does "heroku run python manage.py send_queued_mail" work from command line but not when in a clock.py file for Heroku?

My clock.py below. I can use heroku run python manage.py send_queued_mail all day long but including run python manage.py send_queued_mail in a clock.py file causes a syntax error.

clock.py:

from apscheduler.scheduler import Scheduler

sched = Scheduler()

@sched.interval_schedule(minutes=1)
def timed_job():
    python manage.py send_queued_mail

sched.start()

while True:
    pass

Heroku error message (from log):

2014-01-24T01:31:47.256648+00:00 app[clock.1]:   File "clock.py", line 7
2014-01-24T01:31:47.256648+00:00 app[clock.1]:     run python manage.py send_queued_mail
2014-01-24T01:31:47.256648+00:00 app[clock.1]:              ^
2014-01-24T01:31:47.256648+00:00 app[clock.1]: SyntaxError: invalid syntax

EDIT: management.call_command('send_queued_mail') works from the python shell on heroku, but fails with a "command not found" error when I run it from the clock.py file. I can clearly see send_queued_email.py file where it is supposed to be. And if I run python manage.py help I can see 1send_queued_email` as an available command. Somehow running the command from clock.py is causing heroku to not fond the command.

I finally figured this out. When calling my command from a python file, I needed to explicitly set DJANGO_SETTINGS_MODULE to mysite.settings. Below is the final file for anyone else who ever decides they want to schedule async email sends from a Django app on Heroku with greater frequency than the once-every-5-minutes supported by the Heroku Scheduler add-on.

# clock.py

import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'anonqaproject.settings'

from apscheduler.scheduler import Scheduler
from post_office import utils

sched = Scheduler()

@sched.interval_schedule(minutes=1)
def timed_job():
    utils.send_queued_mail()

sched.start()

while True:
    pass

Because

python manage.py send_queued_mail

is not valid Python code.

You can call a management command programmatically using django.core.management.call_command:

from django.core.management import call_command
call_command('send_queued_mail')
