title: Need more understanding on python fuzz partial ratio
body: <p>I am using python fuzzywuzzy on an enterprise level to match 2 strings. It works fine in most of the cases but giving unexpected results in the below mentioned scenario:</p>
  
  <pre><code>fuzz.partial_ratio('ja rule:mesmerize','ja rule feat. ashanti:mesmerize') gives output 65
  </code></pre>
  
  <p>and</p>
  
  <pre><code>fuzz.partial_ratio('ja rule:mesmerize','jennifer lopez feat. ja rule:im real ') gives the output 67
  </code></pre>
  
  <p>Any explanation on why the fuzz score in the second match is better than the first match?</p>
  
  <p>Any help/suggestion is greatly appreciated.</p>
