[Solved] Identify the error in the following code snippet:from scipy.sparse import csr_matrix mat = csr_matrix([[1, 0], [0, 2]]) mat_csc = mat.tocsc print(type(mat_csc)) | SciPy

SciPy - Sparse Matrices (scipy.sparse)

Identify the error in the following code snippet:

from scipy.sparse import csr_matrix
mat = csr_matrix([[1, 0], [0, 2]])
mat_csc = mat.tocsc
print(type(mat_csc))

AMissing parentheses when calling tocsr()

BMatrix initialization syntax error

CIncorrect import statement

DMissing parentheses when calling tocsc()

Step-by-Step Solution

Solution:

Step 1: Check method call syntax
The code uses mat.tocsc without parentheses, so it references the method, not calls it.
Step 2: Correct method call
Adding parentheses mat.tocsc() calls the method and returns the converted matrix.
Final Answer:
Missing parentheses when calling tocsc() -> Option D
Quick Check:
Method call needs parentheses [OK]

Quick Trick: Always add () to call conversion methods [OK]
