title: programming style conventions: [+], [-], [*], [!]
body: <p>I couldn't find an answer through google search because apparently google won't allow searches for punctuation. </p>
  
  <p>When reporting stdout of a program (I'm using Python), does anyone have any style rules for <code>[+]</code> <code>[-]</code> <code>[*]</code> <code>[!]</code> at the beginning of a line? e.g.</p>
  
  <pre><code>[+] Searching for item one...
  [-] Not found: item one.
  [+] Searching for item two...
  [!] Found: item two.
  </code></pre>
  
  <p>I could come up with a system myself, but because I see these around occasionally, I was wondering whether someone knew of a generally accepted system for usage?</p>
