Well, I can at least answer this question. When you type at the sage:
prompt, or in the notebook, the input is run through the "preparser";
this transforms the input from Sage's extended Python syntax into
standard Python.
You can see what it does using the preparse function:
sage: preparse('3')
'Integer(3)'
sage: preparse('3.14159')
"RealNumber('3.14159')"
