title: Datamatrix code generation with python
body: <p>I need to "encode" a string into a <a href="http://en.wikipedia.org/wiki/Data_Matrix" rel="nofollow">Datamatrix code</a> image, and am struggling the whole day to find a way (library) to do it.</p>
  
  <p>Does anyone know a good python library for Datamatrix code generation? Or a way to do it?"</p>
  
  <p>Thanks!</p>
