title: Trouble understanding schedule
body: <p>I'm trying to get my head around schedule. I've looked at <a href="https://stackoverflow.com/questions/373335/how-do-i-get-a-cron-like-scheduler-in-python">How do I get a Cron like scheduler in Python?</a> and have altered the code but cannot figure out why</p>
  <pre><code>import schedule
  import time
  
  def job():
      print(&quot;I\'m doing the job&quot;)
  
  schedule.every().minute.at(&quot;:17&quot;).do(job)
  
  while True:
      schedule.run_pending()
      time.sleep(1)
  </code></pre>

  <pre><code>I'm doing the job
  I'm doing the job
  I'm working...
  I'm working...
  I'm doing the job
  I'm working!
  I'm working...
  I'm working...
  I'm working...
  I'm working!
  I'm working!
  I'm working...
