Hi Brandon,
You are getting the error since the scripts ending in .py are not
preparsed. For example, the integer 104 is a Python integer. The
Sage interpreter wraps it with a Integer() so that it becomes a Sage
integer. To see this, try
sage: preparse('vector(104, 1117, 386])')
It's one of those things that you need keep in mind when writing
Python scripts that use Sage. An alternative would be to write a
vectest.sage file which would get preparsed.
