title: Run python file -- what function is main?
body: <p>I have simple python script, 'first.py':</p>
  
  <pre><code>#first.py
  def firstFunctionEver() :
      print "hello"
  
  firstFunctionEver()
  </code></pre>
  
  <p>I want to call this script using : <code>python first.py</code> and have it call the <code>firstFunctionEver()</code>. But, the script is ugly -- what function can I put the call to <code>firstFunctionEver()</code> in and have it run when the script is loaded?</p>
