When I type this line

from sage.rings.number_field.splitting_field import SplittingData

in Sage, I get the following error message:

Traceback (click to the left of this block for traceback)
...
ImportError: No module named splitting_field

I see in the online documentation that splitting fields of polynomials over number fields is very recent in Sage:

Hello,

I edited your question so that it is actually a question, not just a quick copy-paste.

It seems that you have noticed in the online documentation that the code for splitting fields over number fields is very recent in Sage.

As a consequence, it will only work if you are using a recent version of Sage, which includes these changes. For instance, in Sage 6.1.1 the command you tried will work, but in Sage 5.12 it will not.

What version of Sage are you using? If you are able to, you should install Sage 6.1.1.
