title: Python3.4: for each line in text
body: <p>I have this code:</p>
  
  <pre><code>for x in adele_text:
      if "Hello, its me" in x:
          print (x)
  </code></pre>
  
  <p>It prints the line where "Hello, its me" is. I would like to be able to print the next line, and the line after this one. How can I print the next x each lines and maybe the x lines before that?</p>
  
  <p>Would there be a way to print the last 2 sentences? Sentences are seperated with a "."</p>
