title: Retrieve first word in parenthesis in Python
body: <p>I googled and read up on some codes here <a href="https://stackoverflow.com/questions/4894069/regular-expression-to-return-text-between-parenthesis">Regular expression to return text between parenthesis</a> </p>
  
  <p>but say for example I have the following string</p>
  
  <p>"[Guide] Strength (STR) is recommended on Warriors (Warriors -> Berserker)"</p>
  
  <p>How would I output "STR" only and not (Warriors -> Berserker) ?</p>
  
  <p>Thanks!</p>
