Description
We provide a method to compute the basis for the derivations of an algebra.
The next step after this will be to construct the derivations as a Lie algebra as a separate parent.

ok. You can set to positive if you agree with my last commit, fixing more pyflakes warnings (but not the last one, which is more subtle).
