title: easy save/load of data in python
body: <p>What is the easiest way to save and load data in python, preferably in a human-readable output format?</p>
  
  <p>The data I am saving/loading consists of two vectors of floats. Ideally, these vectors would be named in the file (e.g. X and Y).</p>
  
  <p>My current <code>save()</code> and <code>load()</code> functions use <code>file.readline()</code>, <code>file.write()</code> and string-to-float conversion. There must be something better.</p>
