title: Python - IndentationError: expected an indented block (Unusual Indentation Error involving a class)
body: <p>While trying to develop a class, I got this error.</p>
  
  <pre><code>from __future__ import division
  import numpy as np
  import scipy as sp
  import itertools as it
  from scipy.integrate import quad
  import astropy.cosmology
  from astropy import units as u
  
  class NFW:  
  
  File "/Users/alexandres/Illustris/Scripts/NFWprofile2.py", line 10
  
                 ^
  IndentationError: expected an indented block
  [Finished in 0.1s with exit code 1]

  [dir: /Users/alexandres/Illustris/Scripts]
  [path: /usr/bin:/bin:/usr/sbin:/sbin]
  </code></pre>
  
  <p>How is this an indentation error?</p>
  
  <p>regardless if i define the class as <code>NFW()</code> or <code>NFW(object)</code>, this is occurring.</p>
