Is this the LinearAlgebra package from Numeric? It's helpful if you don't assume we know what you are talking about :-) If so, shouldn't it be something like from Numeric.LinearAlgebra import * ? Anyway my guess is that you have another program called LinearAlgebra.py in your python path. *That* program probably has the correct import, but it also does some calculations and prints the result. Try this: import LinearAlgebra print LinearAlgebra.__file__ to find out what you are really importing.
