title: How to collect all cameras in Maya using Python?
body: <p>How can I collect all the cameras in a Maya scene excluding the default 'perspective, top, front, side' cameras?</p>
  
  <p>I only want to collect the user created cameras.</p>
  
  <pre><code>cameras = cmds.ls(type=('camera'), l=True) or []
  print cameras
  </code></pre>
  
  <p>Do I need to do <code>listRelatives</code> for any reason? I eventually just want to print the world Matrix of each camera.</p>
