Replying to [comment:6 saraedum]:
> I just bumped into this bug myself. Wouldn't it make more sense to make
coordinates() return an empty tuple instead? I believe this makes sense
since 0 is in the zero-dimensional vector space.
Yep, in vector spaces:
{{{
sage: V = QQ^1
sage: W = V.subspace([0])
sage: W.coordinates(0)
[]
sage: W.coordinates(1)
TypeError
}}}
