title: Python/Pandas: Counting the number of times a value less than x appears in a column
body: <p>Hi I have a file of variables that I have read in as sim.</p>
  
  <pre><code>&gt;&gt;sim.head()
          SIM0    212321
          SIM1    9897362
          SIM2    345
          SIM3    2345
          SIM4    79727367
  </code></pre>
  
  <p>I have assigned the first value of the column to original:</p>
  
  <pre><code>original=sim[0]
  212321
  </code></pre>
  
  <p>I would like to use pandas to count the number of times a number less than 212321 appears in sim.
  Is there a way to do this without a loop?</p>
