title: How can I classify data with the nearest-neighbor algorithm using Python?
body: <p>I need to classify some data with (I hope) nearest-neighbour algorithm. I've googled this problem and found a lot of libraries (including PyML, mlPy and Orange), but I'm unsure of where to start here. </p>
  
  <p>How should I go about implementing k-NN using Python?</p>
