title: Importing a data set in python
body: <p>I am writing a code that requires me to import a set of data. Where in my python folder do I save the data so that the program will recognize it?</p>
  
  <p>Here is a snippit from my code:</p>
  
  <pre><code> from matplotlib.pylab import *
   from scipy import optimize
  
   # Read in the data, storing it as two 1D arrays, time and speed
   freefall=loadtxt('freefall.data')
   time  = freefall[:,0]
   speed = freefall[:,1]
  </code></pre>
  
  <p>The data file that I am trying to import is freefall.data.</p>
