In NumPy, these functions are essential for initializing arrays efficiently:
-
np.zeros((3,3)): Creates a 3×3 array of zeros. -
np.ones((3,3)): Creates a 3×3 array of ones. -
np.empty((3,3)): Creates an uninitialized array (filled with random values from memory).
Use empty() when performance matters and initialization isn’t needed. Learning how to use these functions effectively is a key topic in the Best Python Course because they form the foundation for numerical computing, data preprocessing, and scientific analysis.
