I can exclude a list of items by using negative index in R (R-project) ie
myarray[-excludeindex]. As negative indexing in numpy (And python) behave

You can make a mask array in numpy to prune out items from an array
that you don't want, denoting indices you want to keep with 1's and
those you don't want to keep with 0's. For instance,
a = np.array([1,3,45,67,123])
mask = np.array([0,1,1,0,1],dtype=np.bool)
anew = a[mask]
will set anew equal
