title: How to check if a number in a list is greater than the number before it - python
body: <p>I have 3 sets of data zipped together (date,somenumber,price). I want to iterated through the table and whenever somenumber is less than somenumber before it in the list I want to pull the date,somenumber,price for when that happens. Currently I just have:</p>
  
  <pre><code>for a,b,c in zip(date,somenumber,price):
      print(a,b,c)
  </code></pre>
  
  <h1>and it prints something like:</h1>
  
  <pre><code>2018-01-30 18:42:00 859235 6.95
  2018-02-01 09:08:00 323405 7.43
  2018-02-02 15:16:00 528963 6.4
  2018-02-05 18:48:00 808739 7.91
  2018-02-07 14:42:00 462541 7.33
  2018-02-10 18:48:00 598001 6.21
  2018-02-11 03:32:00 650558 7.31
  2018-02-11 11:28:00 670392 6.21
  </code></pre>
  
  <p>When somenumber went from 808739 to 462541 I want to return the data for that lower number:
  2018-02-07 14:42:00 462541 7.33</p>
  
  <p>Thanks!</p>
