title: Finding a sequence of characters in string
body: <p>Using python, I am trying to find any sequence of characters in a string by specifying the length of this chain of characters. </p>
  
  <p>For Example, if we have the following variable, I want to extract any identical sequence of characters with a length of 5:</p>
  
  <pre><code>x = "jhg**11111**jjhgj**11111**klhhkjh111ljhjkh1111"
  </code></pre>
  
  <p>the result should be:</p>
  
  <pre><code>11111
  11111
  </code></pre>
  
  <p>how can I do that?</p>
