title: Python not equal operator
body: <p>I come from a c style languages, so I am natural in using <code>!=</code> as not equal, but when I came to Python, from the documentation I read, I learned that for this purpose the <code>&lt;&gt;</code> operator is used. </p>
  
  <p>Recently, I have seen a lot of code using <code>!=</code>, so my question is if one of them is preferred  over the other or is one of them deprecated.</p>
  
  <p>Also, I would like to know if there is any difference between them.</p>
