Output

The program you provided uses NumPy to create a 3-dimensional array and then attempts to index into this array. Let's break it down step by step to understand what it will print: 1. `array = np.zeros((10, 20, 30))`: This creates a 3-dimensional NumPy array of shape `(10, 20, 30)` filled with zeros. 2. `idxs = [1, 2, 3]`: This creates a list of indices `[1, 2, 3]`. 3. `array[0, :, idxs]`: This uses advanced indexing to select elements from the array. Let's understand this indexing: - `0` selects the first element along the first dimension (of size 10). - `:` selects all elements along the second dimension (of size 20). - `idxs` selects the elements at positions 1, 2, and 3 along the third dimension (of size 30). So, `array[0, :, idxs]` will result in selecting the elements at positions 1, 2, and 3 along the third dimension for all elements along the second dimension in the slice where the first dimension is 0. This will give an array of shape `(20, 3)` because: - There are 20 elements in the second dimension. - For each of these 20 elements, 3 elements are selected from the third dimension (as specified by `idxs`). Therefore, the shape of the resulting array is `(20, 3)`. Thus, the program will print: 

1
The array shape is (20, 3)

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

Output

The provided Python program uses the `numpy` library to create a three-dimensional array and then prints the shape of a specific slice of this array. Let's break down the relevant parts of the code step by step: 1. **Array Creation:** 

1
2
   array = np.zeros((10, 20, 30))
This line creates a 3D array of shape (10, 20, 30) filled with zeros. 2. **Index List:** 
1
2
   idxs = [1, 2, 3]
This line defines a list of indices. 3. **Array Slicing and Shape Calculation:** 
1
2
   print("The array shape is", array[0, :, idxs].shape)
Here, `array[0, :, idxs]` slices the array: - `0` selects the first element along the first dimension (reducing the shape from (10, 20, 30) to (20, 30)). - `:` selects all elements along the second dimension. - `idxs` selects the elements at indices 1, 2, and 3 along the third dimension. The result of `array[0, :, idxs]` will have the shape: - The first dimension (20) remains unchanged since we are selecting all elements along this dimension. - The second dimension will be reduced to 3, as we are selecting 3 specific indices from the third dimension. Therefore, the shape of `array[0, :, idxs]` will be (20, 3). 4. **Output:** The program will print: 
1
2
   The array shape is (20, 3)
So, when you run this program, it will print: 
1
The array shape is (20, 3)

Output

The given Python program uses NumPy to create a 3-dimensional array of zeros with a shape of \( (10, 20, 30) \). It then defines a list of indices `idxs` as `[1, 2, 3]` and prints the shape of a sliced portion of the array. Let's break down the slicing operation `array[0, :, idxs]`: 1. `array[0, :, idxs]`: - `0` selects the first element along the first axis (reducing the shape from \( (10, 20, 30) \) to \( (20, 30) \)). - `:` selects all elements along the second axis (still \( (20, 30) \)). - `idxs` selects the 1st, 2nd, and 3rd elements along the third axis. Since `idxs` has 3 elements, the shape of the third axis is reduced to 3. So, the resulting shape of `array[0, :, idxs]` will be \( (20, 3) \). Thus, the program will print: 

1
The array shape is (20, 3)

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

Output

The program will print the shape of the sliced NumPy array. Let's break down the slicing operation to understand the resulting shape. 1. `array` is initialized as a 3-dimensional array of zeros with the shape `(10, 20, 30)`. 2. `idxs` is a list containing the values `[1, 2, 3]`. 3. The slicing operation `array[0, :, idxs]` means: - `0` in the first dimension: This selects the first "slice" along the first axis, reducing the dimensionality from `(10, 20, 30)` to `(20, 30)`. - `:` in the second dimension: This selects all elements along the second axis. - `idxs` (which is `[1, 2, 3]`) in the third dimension: This selects the elements at indices 1, 2, and 3 along the third axis. Therefore, `array[0, :, idxs]` effectively selects elements from a shape `(20, 30)` array where the third axis is indexed by `[1, 2, 3]`. The shape of the resulting array will be `(20, 3)` because: - The second dimension (`:`) remains the same with size 20. - The third dimension is reduced to the length of `idxs`, which is 3. So, the program will print: 

1
The array shape is (20, 3)

1
2
   import numpy as np
2. **Creating a numpy array:** 
1
2
   array = np.zeros((10, 20, 30))
This creates a 3-dimensional numpy array of shape `(10, 20, 30)` filled with zeros. 3. **Indexing:**

2
   idxs = [1, 2, 3]
`idxs` is a list containing the indices `[1, 2, 3]`. 4. **Slicing the array:** 
1
2
   array[0, :, idxs]
Here, `array[0, :, idxs]` means: - `0` selects the first element along the first axis (reducing the shape from `(10, 20, 30)` to `(20, 30)`) - `:` selects all elements along the second axis (keeping the shape as `(20, 30)`) - `idxs` selects elements at positions 1, 2, and 3 along the third axis (reducing the shape from `(20, 30)` to `(20, 3)`) 5. **Printing the shape:** 
1
2
   print("The array shape is", array[0, :, idxs].shape)
Putting it all together, the code will print the shape of the sliced array. The resulting shape after the slicing operation is `(20, 3)`. Therefore, the program will print: 
1
The array shape is (20, 3)
