is python Object oriented??
Object oriented languages doesn't allow execution of the code without class objects, what is actually happening when we execute some piece of code, is it bound to any class?

Re: is python Object oriented??
but still I am not clear of the execution of the code, when we write or execute a piece of python code without defining class, predefined class attributes are available (not all but __name__ and __doc__ are available). does it mean anything to this topic. Is it necessory to have __module__, __dict__ and __bases__ for a class object in python?

Hi Chris, Thanks for quick and kind reply, but the python program runs on the server, sys.platform is linux only.

Re: os module
Oh that might be the problem, I m new to this and new to this kind of conversations. What you said was correct. But what I am looking for is, if one client reqst comes I need to process the data which I got from the client, so I need to use the os module. But since my program executes on the server os.sys.platform has the value "linux2". What I want is a module having clients platform value for os.sys.platform. Any way to get that?

Re: os module
Its just http, I am using pylons. Right now I am doing tht with extra parameter. But even if I get to know about the platform of the client machine, I need to use the other properties of the corresponding machine's os module. for example I need to use "os.path". So even if I know about the platform name how to use that information to get os module with the property of tht particular platform.
