Python Vs Ruby On Rails : on Size
I personally prefer Python/django. Size is small given u have necessary things installed.
I am planning to do a small web application that will be distributed as a single installable. I have plans to develop this application in either Python/Django or Ruby On Rails. (I am a Java/C++ programmer, hence both these languages are new to me). 
My main concern is about the size and simplicity of final installable (say setup.exe). I want it to be small in size and also should be able to pack all required components in it. 
Which one among Python/Django and Ruby On Rails is suitable for me?
