A Flatten a NumPy Array?
Code Explanation:
● Array Initialization: A 2D array arr of shape (2, 2) is created.
● Flatten Operation: arr.flatten() converts the 2D array into a 1D array.
● New Shape: The resulting array has shape (4,) — all values in a single line.
● No Change to Original: flatten() returns a copy, original array remains unchanged.
● Display: The flattened array is printed.
Program:
import numpy as np
arr = np.array([[1, 2], [3, 4]])
flat = arr.flatten()
print(flat)
