title: How do I open a .py file in python from a .py file in pypy?
body: <p>My program currently consists of 2 .py files. </p>
  
  <p>I run the main part of the code in pypy (which is much faster) and then I open a second file in python that plots my data using <code>matplotlib.pyplot</code>.</p>
  
  <p>I have managed to open the using: </p>
  
  <pre><code>subprocess.Popen(['C:\\python26\\python.exe ','main_plot.py',])
  </code></pre>
  
  <p>which opens my second file...</p>
  
  <pre><code>import matplotlib.pyplot as pyplot
  def plot_function(NUMBER):
      '''some code that uses the argument NUMBER'''
      pyplot.figure()
      ---plot some data---
      pyplot.show()
  </code></pre>
  
  <p>However, I would like to be able to pass arguments to the <code>plot_function</code> that opens in python. Is that possible?</p>
