title: how to remove first x characters from a string in a list
body: <p>So I have a list and a couple of string in it. I just want to remove the first 7 characters from each of the strings. How do I do that?</p>
  
  <p>I've tried:</p>
  
  <pre><code>lst = ["1234567something", "1234567smthelse"]
  
  for i in lst:
  
      i [7:]
  
  print lst
  </code></pre>
  
  <p>But I get the same list from the beginning...</p>
