type(3) <type 'sage.rings.integer.Integer'>

So how was sage's python version created, and do I need to learn C to be able to do that ? I would like some easy to begin guide, on how to achienve the same basic things as I'd like to know it's internal workings.

You definitely don't need to learn C!

Sage is indeed preparsing the entries before sending them to Python. To know what Sage is doing exactly with what you are typing, use the command preparse, with your Sage command passed as a string:

sage: preparse("3")
'Integer(3)'
sage: preparse("3+2")
'Integer(3)+Integer(2)'
sage: preparse("x^2")
'x**Integer(2)'

Yes. And beyond the preparsing and adding lots of functions, there are a few other things that are (slightly) redefined like sum which expand their usefulness. For 99% of purposes Sage can be thought of as Python with extra sugar.
