title: celery beat schedule arguments
body: <pre><code>CELERYBEAT_SCHEDULE = {
  
      'task every 20 seconds': {
          'task': 'tasks.function',
          'schedule': timedelta(seconds=20),       
          'args': [argument] 
       },
  
  }
  </code></pre>
  
  <p>My function takes one argument. But I want to call it for more than one argument on one worker. How can I call different arguments in  "args:" or what I must do for define multiple arguments.</p>
