title: x.strip() with for in python
body: <p>I have a python line which is :</p>
  <pre><code>start_codon=[x.strip()
               for x in start_codon.split(&quot;,&quot;)]
  </code></pre>
  <p>can anybody explain what is the use of x.strip() combined with the &quot;for&quot;
  I can see that the result of just doing start_codon.split(&quot;,&quot;) will be the same as writing the entire line</p>
