print("The array shape is", array[0, :, idxs].shape)

Output

Let's solve this step by step: 1) First, `array = np.zeros((10, 20, 30))` creates a 3D NumPy array with dimensions 10 x 20 x 30, filled with zeros. 2) `array[0, :, idxs]` does the following: - `0` selects the first slice in the first dimension - `:` selects all elements in the second dimension - `idxs` (`[1, 2, 3]`) selects specific indices in the third dimension 3) This means the resulting slice will have: - First dimension: 1 slice (from index 0) - Second dimension: all 20 elements - Third dimension: 3 elements (from indices 1, 2, 3) 4) So the shape will be `(20, 3)` Therefore, the program will print:

1
The array shape is (20, 3)
The code demonstrates NumPy's flexible indexing, where you can select specific slices and indices across different dimensions.

Let's solve this step by step: 1) `array = np.zeros((10, 20, 30))` creates a 3D NumPy array with dimensions 10 x 20 x 30, filled with zeros. 2) `idxs = [1, 2, 3]` defines a list of indices. 3) `array[0, :, idxs]` means: - Select the 0th slice in the first dimension - Select all slices in the second dimension (`:`) - Select the 1st, 2nd, and 3rd indices in the third dimension 4) So the resulting slice will have: - First dimension is size 1 (from the 0th slice) - Second dimension is size 20 (all slices) - Third dimension is size 3 (from the `idxs` list) 5) Therefore, the shape will be `(20, 3)` So this program will print:

1
The array shape is (20, 3)
The key is understanding how NumPy indexing works with lists of indices in different dimensions.

2
   The array shape is (20, 3)
   
The key point is that when you index a NumPy array with a list of indices in one dimension, it reduces that dimension to the length of the index list.

print("The array shape is", array[0, :, idxs].shape)

Output

Let's solve this step by step: 1) The original array `array` is a 3D numpy array with shape (10, 20, 30), created with all zeros using `np.zeros()`. 2) The indexing `array[0, :, idxs]` means: - First dimension is fixed at index 0 - Second dimension `:` means take all elements - Third dimension uses `idxs`, which is `[1, 2, 3]` 3) So this slice will select: - The 0th slice in the first dimension - All slices in the second dimension - The 1st, 2nd, and 3rd slices in the third dimension 4) The resulting shape will be: (20, 3) - 20 comes from the second dimension (`:`) - 3 comes from the length of `idxs` Therefore, the program will print:

1
The array shape is (20, 3)

Let's solve this step by step: 1) First, `array = np.zeros((10, 20, 30))` creates a 3D NumPy array with dimensions 10 x 20 x 30, filled with zeros. 2) When you do `array[0, :, idxs]`, this means: - Select the 0th element along the first dimension - Select all elements along the second dimension (`:`) - Select elements at indices 1, 2, 3 along the third dimension 3) So the resulting subarray will have dimensions: - First dimension: 1 (because you selected the 0th element) - Second dimension: 20 (because you selected all elements) - Third dimension: 3 (because you selected 3 indices) 4) Therefore, the shape will be `(20, 3)` The output will be:

1
The array shape is (20, 3)
