title: String similarity (semantic meaning) in python
body: <p>How can I calculate the string similarity (semantic meaning) between 2 string?</p>
  
  <p>For example if I have 2 string like "<strong>Display</strong>" and "<strong>Screen</strong>" the string similarity must be close to 100%</p>
  
  <p>If I have "<strong>Display</strong>" and "<strong>Color</strong>" the screen similarity must be close to 0%</p>
  
  <p>I'm writing my script in Python... My question is if exists some library or framework to do this kind or think... In alternative can someone suggest me a good approach?</p>
