title: Importing mutable variables from one python code to another
body: <p>I have two Python codes. Code <code>Python_A</code> consists of a function and returns values <code>val1</code>, <code>val2</code>, <code>val3</code>. Code <code>Python_B</code> consists of a function whose argument values have to be <code>arg1 = val1</code>, <code>arg2 = val2</code>, <code>arg3 = val3</code>. How do I implement this?</p>
  
  <p>The sequence of steps in which I would want this to happen is:  </p>
  
  <ol>
  <li>Code <code>Python_A</code> is executed </li>
  <li>Submit a PBS job to a multiprocessor cluster
  which invokes a function from code <code>Python_B</code> that has to have its arguments as <code>val1</code>, <code>val2</code>, <code>val3</code>.</li>
  </ol>
  
  <p>Several posts have shown ways of importing stationary values from one python code into another. But, none could be found which show importing mutable values. </p>
  
  <p>How to get this right?</p>
