title: Python How to share a List array between two scripts using mmap but without using files?
body: <p>How can I share a list <strong>between two python scripts</strong> using <code>mmap</code> but <strong>without using files</strong>?</p>
  
  <p>My first python script calls the other using <code>subprocess.Popen(["python","child.py"])</code> </p>
  
  <p>I have to call 10 different subprocess and don't want to use a file as it will increase I/O time which is not desirable.</p>
  
  <p>Each of my subprocess will modify this list variable created in the parent process.</p>
  
  <p>Note: I don't want to use <code>multiprocess</code> or <code>threads</code> and require the solution using <code>subprocess.Popen</code> only.</p>
