SciPy - Sparse Matrices (scipy.sparse)
Which of the following is the correct syntax to convert a SciPy sparse matrix
mat to CSR format?Which of the following is the correct syntax to convert a SciPy sparse matrix mat to CSR format?
easy📝 Syntax Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Recall SciPy conversion methods
Sparse matrices have methods liketocsr()to convert to CSR format.Step 2: Check syntax correctness
mat.tocsr()is the correct method;to_csr()andconvert()do not exist;csr_matrix(mat)creates a new matrix but is less direct.Final Answer:
mat.tocsr() -> Option AQuick Check:
Correct method = tocsr() [OK]
Quick Trick: Use .tocsr() method to convert sparse matrix to CSR [OK]
Common Mistakes:
MISTAKES- Using incorrect method names like to_csr()
- Trying to use convert() method which doesn't exist
- Confusing constructor with conversion method
