title: Extract number from a list in Python
body: <p>I am using Python v2.x Windows 64bit.
  The question is, I would like to extract a number (102) from a list, but I can only get a part of if.</p>
  
  <p>Here is a list: </p>
  
  <pre><code>data = ['getmotors \r', 'Parameter,Value\r', 'Brush_RPM,0\r', 'Brush_mA,0\r', 'Vacuum_RPM,0\r', 'Vacuum_mA,0\r', 'LeftWheel_RPM,1800\r', 'LeftWheel_Load%,42\r', 'LeftWheel_PositionInMM,10452\r', 'LeftWheel_Speed,102\r', 'RightWheel_RPM,1800\r', 'RightWheel_Load%,42\r', 'RightWheel_PositionInMM,9650\r', 'RightWheel_Speed,102\r', 'ROTATION_SPEED,0.00\r', 'SideBrush_mA,0\r', '\x1a']
  </code></pre>
  
  <p>How to extract the speed of LeftWheel_Speed (102)?
  I tried <code>data[9][-2]</code>, but what I get is ‘<code>2</code>’ rather than ‘<code>102</code>’.</p>
