scipy.sparse.dok_array.update# dok_array.update([E, ]**F) → None. Update D from dict/iterable E and F.[source]# If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]
