title: How to open a .data file extension
body: <p>I am working on side stuff where the data provided is in a <code>.data</code> file. How do I open a <code>.data</code> file to see what the data looks like and also how do I read from a <code>.data</code> file programmatically through python? I have Mac OSX</p>
