title: Pass python session to a script written with another version of python
body: <p>For example, if I have:</p>
  
  <p>(1) ScriptA, written in 2.X as it needs 2.X libraries</p>
  
  <p>(2) ScriptB, written in 3.X, as it needs 3.X libraries</p>
  
  <p>Is there a way to do the following?:</p>
  
  <p>-> ScriptA calls scriptB (switching Python version), passing a session object without serializing it.</p>
  
  <p>Using a command line makes it possible to switch python version, but without the possibility of passing a session object...</p>
  
  <p><strong>-- EDIT --</strong></p>
  
  <p>By session, I mean for example that I have an opened TCP/IP connection to a given server, and I don't want to open a new one in the second script</p>
