Python Coding - Sample Uniformly From a grid

I am new to python so wanted some help. Basically I have an 11 D vector \theta and I need to uniformly sample from the space of thetas such that distance between each \theta is \eta (Basically over a grid of \eta), but the fact that each theta is a vector of 11D is confusing me, as to how to go about it? Any leads will be appreciated!
