That's an indication that you're running python "with sage imported". The
sage notebook and sage's IPython command line interface also run input
strings through "preparse". Example:
sage: preparse("[1..10]")
'(ellipsis_range(Integer(1),Ellipsis,Integer(10)))'

Indeed, the preparser also puts "Integer(...)" around any integer constant,
to ensure that sage defaults to its own Integer type rather than python's
"int".
Probably the most easily recognized difference is:
sage: 2^3 #exponentiation
8
versus python's
>>> 2^3 #exclusive or
1
I use " import sys and from sage.all import * " at the start of my code.

This means that the environment you have created is very similar to the one
in which you have to work when you're writing sage library code (which
doesn't get preparsed either), which is really rather appropriate given
that eclipse is a software development environment.
