Dear Danny, Thank for your invaluable advice which is much appreciated. My code finally ends up being exe-fied with py2exe and I have a bit of a limitation there. I have to select packages which are compatible with it. Haven't tried json or checked whether it is compatible but I will do so. On another note which is a better exe-fier? py2exe or cxfreeze? I would like your personal opinion if you have any knowledge on this matter. Thank you once again for your invaluable help.
