An agricultural engineer is writing a Python program to populate a 4×4 4 \times 4\,4×4 2D array representing a grid of soil moisture readings. Each cell in the grid is filled with a moisture value returned by the function get_moisture().
Complete the Python program in the code block below by filling in the five gaps on lines 9, 12, 14, and 16 so that the array is correctly populated.
1 moisture_grid = [ [0.0, 0.0, 0.0, 0.0],
2 [0.0, 0.0, 0.0, 0.0],
3 [0.0, 0.0, 0.0, 0.0],
4 [0.0, 0.0, 0.0, 0.0] ]
