title: Is there a way in Python to exit the program if the line is blank?
body: <p>My file is a .txt file and all comments have no spaces before them.</p>
  
  <p>I have a file with 10,000 lines that looks like this and I am reading every line of the file.</p>
  
  <pre><code>## something
  ## something
  ## something
  12312312
  123123
  12312312
  123123
  123123
  </code></pre>
  
  <p>However, my code will fail if there is not a value in every line.</p>
  
  <p>Is there a way in Python to exit the program if the line is blank?</p>
  
  <p>I just need a simple If statement to fix my program.</p>
  
  <p>Something like </p>
  
  <pre><code>if line == blank:
      quit
  </code></pre>
