Output

This program creates a 3-dimensional NumPy array with the shape of `(10, 20, 30)`. It then attempts to access a subset of this array using slicing and advanced indexing. In the line `array[0, :, idxs]`, the program is doing the following: - `0` selects the first element along the first dimension. - `:` selects all elements along the second dimension. - `idxs`, which is the list `[1, 2, 3]`, selects elements at positions 1, 2, and 3 along the third dimension. Therefore, the resulting sub-array will have: - All elements along the second dimension (20 elements) - Three elements along the third dimension (because of the indices 1, 2, 3) - The first dimension is effectively removed because a specific index `0` is selected. The shape of the resulting array will be `(20, 3)`, where 20 comes from the second dimension (since all elements were selected) and 3 comes from the length of `idxs` (selecting three positions along the third dimension). The program will print:

1
The array shape is (20, 3)

Output

This Python program uses the NumPy library to create a multidimensional array and then access a specific part of it using indexing. The initial array is a 3D array with dimensions \(10 \times 20 \times 30\), created by `np.zeros((10, 20, 30))`. The statement `array[0, :, idxs]` selects: - From the first dimension: the slice at index `0`, which reduces the array to a \(20 \times 30\) 2D array because you've selected one specific "page" or "layer" of the 3D array. - From the second dimension: all elements (indicated by `:`), so it retains all 20 rows. - From the third dimension: only the elements at the indexes specified in `idxs`, which are `[1, 2, 3]`. This means it selects the 2nd, 3rd, and 4th elements from the third dimension since indexing in Python is 0-based. So, the resultant subarray has dimensions corresponding to the size of the second dimension (which remains unchanged at 20) and the size of the `idxs` list (which has 3 elements). Therefore, the shape of the subarray will be `(20, 3)`. The program will print:

1
The array shape is (20, 3)

Output

To determine what the program prints, let's break down the operations: 1. A 3-dimensional NumPy array of shape `(10, 20, 30)` is created using `np.zeros`. This means the array has 10 elements in the first dimension, 20 in the second, and 30 in the third. 2. A list of indices `idxs = [1, 2, 3]` is defined. 3. The program accesses a sub-array of `array` using slicing and indexing: `array[0, :, idxs]`. - `0` selects the first element along the first dimension. - `:` selects all elements along the second dimension. - `idxs` selects elements at indices 1, 2, and 3 along the third dimension. Given these operations, the shape of the resulting sub-array will be determined by the sizes of the dimensions that are fully included (`:` selects all elements of the corresponding dimension) and the number of indices specified for the dimensions where specific indices are provided. - The first dimension is reduced to a single element because of the `0` index, effectively removing it from the shape of the output. - The second dimension is fully included, so it retains its size of `20`. - The third dimension is accessed with 3 specific indices `[1, 2, 3]`, so it will have 3 elements. Therefore, the shape of `array[0, :, idxs]` is `(20, 3)`. The program will print:

1
The array shape is (20, 3)

Output

To understand what this program will print, let's break down the elements involved. 1. **`np.zeros((10, 20, 30))`** creates an array filled with zeros with the shape of (10, 20, 30). This means the array has 10 "layers", each of size 20x30. 2. **`idxs = [1, 2, 3]`** is a list of indices. 3. When accessing **`array[0, :, idxs]`**, the program is doing the following: - **`0`** selects the first layer of the 10 (indexing starts at 0). - **`:`** indicates selecting all elements in the second dimension (all 20 rows). - **`idxs`** indicates selecting the columns at indices 1, 2, and 3 in the third dimension. This operation results in selecting a 20x3 section from the first layer of the array. The 20 comes from the second dimension being fully selected (all rows), and the 3 comes from selecting the three specific indices in the third dimension (columns). Thus, the shape of the resulting array will be **`(20, 3)`**, and the program will print:

1
The array shape is (20, 3)

Output

To determine what the program will print, let's break it down step by step: 1. **Array Creation**: An array of shape `(10, 20, 30)` is created using `np.zeros`, meaning it has 10 arrays within it, each of which is a 2D array of shape `(20, 30)`. 2. **Indexing**: The program then accesses the array using `array[0, :, idxs]`. - The first index `0` selects the first 2D array out of the 10, resulting in a `(20, 30)` array. - The second index `:` means all elements along the first axis of the resulting `(20, 30)` array are selected, so we still consider all 20 rows. - The third index `idxs` is a list `[1, 2, 3]`. This selects the 2nd, 3rd, and 4th elements along the last axis (the columns) of each of the 20 rows. Putting it together, `array[0, :, idxs]` selects a `(20, 3)` shaped array, because: - From the first dimension, we have chosen one specific 2D array, reducing the dimension from 3D to 2D. - We keep all elements from the second dimension (20 rows). - From the last dimension, we select only 3 specific elements (columns) as specified by `idxs`. Therefore, the program will print:

1
The array shape is (20, 3)
