title: Converting evdev inputs to understandable information
body: <p>so i have successfully been able to track both mouse and keyboard events using the following code</p>
  
  <pre><code>devices = map(InputDevice, ('/dev/input/event1', '/dev/input/event0'))
  devices = {dev.fd: dev for dev in devices}
  
  for dev in devices.values(): print(dev)
  
  while True:
      r, w, x = select(devices, [], [])
      for fd in r:
              for event in devices[fd].read():
                      print(event)
  </code></pre>
  
  <p>and the data i get from this code when pressing a key or moving the mouse is the following:</p>
  
  <pre class="lang-none prettyprint-override"><code>event at 1550702472.373994, code 00, type 00, val 00
  event at 1550702472.389984, code 00, type 02, val -5
  event at 1550702472.389984, code 01, type 02, val -2
  event at 1550702472.389984, code 00, type 00, val 00
  event at 1550702472.405988, code 00, type 02, val -3
  event at 1550702472.405988, code 00, type 00, val 00
  event at 1550702472.421987, code 00, type 02, val -2
  </code></pre>
  
  <p>my question is how can i convert this data or analyze the numbers to get a good output like an actual key. something like analyzing the 1550702472.xxx number to get a certain key or maybe the numbers following. </p>
  
  <p>UPDATE: when i say print(categorize(event)) i get this:</p>
  
  <pre class="lang-none prettyprint-override"><code>key event at 1550703468.964836, 38 (KEY_L), down
  synchronization event at 1550703468.964836, SYN_REPORT
  event at 1550703469.052829, code 04, type 04, val 458767
  key event at 1550703469.052829, 38 (KEY_L), up
  synchronization event at 1550703469.052829, SYN_REPORT
  relative axis event at 1550703472.093778, REL_Y
  synchronization event at 1550703472.093778, SYN_REPORT
  relative axis event at 1550703472.125780, REL_X
  synchronization event at 1550703472.125780, SYN_REPORT
  relative axis event at 1550703472.141764, REL_X
  </code></pre>
  
  <p>still the same question though, what array can i use to say if KEY_L do this.</p>
