title: Pipe output from shell command to a python script
body: <p>I want to run a <code>mysql</code> command and set the output of that to be a variable in my python script.</p>
  
  <p>Here is the shell command I'm trying to run:</p>
  
  <pre><code>$ mysql my_database --html -e "select * from limbs" | ./script.py
  </code></pre>
  
  <p>Here is the python script:</p>
  
  <pre><code>#!/usr/bin/env python
  
  import sys
  
  def hello(variable):
      print variable
  </code></pre>
  
  <p>How would I accept the variable in the python script and have it print the output?</p>
