title: How to read in and store x,y data from multiple text files (in one directory)
body: <p>I have around 150 text files that I want to load data from and then plot to a scatter graph. Files are being loaded using <code>numpy.loadtxt</code> as follows:</p>
  
  <pre><code>x,y=loadtxt('2.8k to 293k 15102014_rerun 147_0K.txt',skiprows=1,unpack=True,dtype=float,delimiter=",")
  </code></pre>
  
  <p>How can I load the ~150 files from a given folder and plot them all.</p>
