Yes.

SciPi provides scipy.sparse, a "2-D sparse matrix package for numeric data".

There are seven available sparse matrix types:

csc_matrix: Compressed Sparse Column format

csr_matrix: Compressed Sparse Row format

bsr_matrix: Block Sparse Row format

lil_matrix: List of Lists format

dok_matrix: Dictionary of Keys format

coo_matrix: COOrdinate format (aka IJV, triplet format)

dia_matrix: DIAgonal format
