title: python: find value within range in float array
body: <p>I have the following sorted python list, although multiple values can occur:</p>
  
  <pre><code>[0.0943200769115388, 0.17380131294164516, 0.4063245853719435, 
   0.45796523225774904, 0.5040225609708342, 0.5229351852840304, 
   0.6145136350368882, 0.6220712583558284, 0.7190096076050408, 
   0.8486436998476048, 0.8957381707345986, 0.9774325873910711, 
   0.9832076130275351, 0.985386554764682, 1.0]
  </code></pre>
  
  <p>Now, I want to know the index in the array where a particular value may fall:</p>
  
  <p>For example, a value of 0.25 would fall in index <code>2</code> because it is between 0.173 and 0.40. I guess I can go through the list and do this in a for loop but I was wondering if there is some better way to do this which maybe more computationally efficient. I create this array once but have to perform many lookups.</p>
