How can I create and manipulate sparse arrays in Python?
You can use libraries like SciPy or NumPy to create sparse arrays in Python. Would you like a code example?
Yes, please provide a code example using SciPy.
Sure! Here's a simple example:
from scipy.sparse import csr_matrix
# Create a sparse matrix from a dense matrix
dense_matrix = [[0, 0, 3], [4, 0, 0], [0, 5, 0]]
sparse_matrix = csr_matrix(dense_matrix)
print(sparse_matrix)
What are the advantages of using sparse arrays?
Sparse arrays save memory and improve performance when dealing with large datasets that contain many zeros.
