title: Python global variable and wcf solution guidance
body: <p>My question might be  lame since I recently started learning python, following is my question:</p>
  
  <ol>
  <li><p>I am trying to develop a python cross platform app for android and windows, I need how to use a variable defined at App level through out the program (global but not just at module level, it is mainly for passing user id to all forms)</p></li>
  <li><p>A WCF solution for this program, or any alternative technology ( I am new to web building too, but have used WCF previously).</p></li>
  </ol>
  
  <p>Also, global variables is really tough to understand in python since I am from VB; most of the articles I have gone through say that global variables in a module, but what about application level or like variables/classes instantiated at APP class/build Module in a kivy program.</p>
  
  <p>Any hints on how to develop/architecture guidelines or just pointing in right direction to learn them is of great help. </p>
