Standard documentation for Sparsity.get_nz:

 Get the nonzero index for a set of elements.

 get_nz(self) -> [int]
 get_nz(self, int rr, int cc) -> int
 get_nz(self, [int] rr, [int] cc) -> [int]

The index vector is used both for input and outputs and must be sorted by increasing nonzero index, i.e. column-wise. Elements not found in the sparsity pattern are set to -1.
