Output

Let's break down the code step by step to understand what it does and what it will print. 1. The program imports the NumPy library as `np`. 2. It creates a 3D NumPy array named `array` filled with zeros. The shape of this array is `(10, 20, 30)`, meaning it has: - 10 blocks (or layers), - each containing 20 rows, - and each row containing 30 elements. 3. It defines a list `idxs` containing the values `[1, 2, 3]`. 4. The print statement accesses a specific slice of the array: - `array[0, :, idxs]`: - `0` refers to the first block in the first dimension (the first "layer" of the 3D array). - `:` means it takes all 20 rows from that first block. - `idxs` specifies that it selects the columns at indices 1, 2, and 3 from the last dimension (the 30 elements in each row). Given this, the shape of the slice `array[0, :, idxs]` can be determined: - The first dimension (the block) is fixed to 0, so it contributes `1` to the shape. - The second dimension (the rows) is taken as all rows, which is `20`. - The third dimension is determined by the length of `idxs`, which is `3` (since it selects columns at indices 1, 2, and 3). Putting it all together, the shape of `array[0, :, idxs]` will be `(20, 3)`. Therefore, the output of the print statement will be: 

1
The array shape is (20, 3)

Output

Let's break down the code step by step to understand what it will print. 1. **Creating the array**: 

1
2
   array = np.zeros((10, 20, 30))
This line creates a NumPy array of shape `(10, 20, 30)` filled with zeros. 2. **Defining indices**: 
1
2
   idxs = [1, 2, 3]
Here, `idxs` is a list containing the values `[1, 2, 3]`. 3. **Accessing a slice of the array**: 
1
2
   print("The array shape is", array[0, :, idxs].shape)
In this line, we're accessing a specific slice of the `array`. The indexing `array[0, :, idxs]` does the following: - `0` selects the first "page" of the array along the first dimension (10). - `:` selects all elements along the second dimension (20). - `idxs` selects the elements at indices 1, 2, and 3 along the third dimension (30). Therefore, `array[0, :, idxs]` results in a 2D slice of the original 3D array with shape `(20, 3)`, because: - The first dimension is fixed to 1 (from the selection of `0`). - The second dimension has 20 elements (from the selection of `:`). - The third dimension has 3 elements (from the selection of indices `[1, 2, 3]`). 4. **Printing the shape**: The shape of the resulting array slice `array[0, :, idxs]` is `(20, 3)`. Thus, the output of the program will be: 
1
The array shape is (20, 3)

Output

In the provided code, the program creates a NumPy array of shape `(10, 20, 30)` filled with zeros. Then, it defines a list `idxs` that contains the indices `[1, 2, 3]`. Next, the program attempts to access the array with the indexing `array[0, :, idxs]`. Let's break down what this indexing means: 1. `array[0, :, idxs]` is accessing: - The first slice of the first dimension (index `0`), which gives us a 2D array of shape `(20, 30)` from the original array. - The second slice `:` means that we are taking all rows (20 rows in this case). - The third part `idxs` specifies that we want to take the columns at indices 1, 2, and 3 from the second dimension (originally of size 30). The resulting shape after this indexing will be: - The first dimension remains `20` (since we are taking all rows). - The second dimension will be the length of `idxs`, which is `3` (because we are selecting columns at index `1`, `2`, and `3`). Thus, the resulting shape of the sliced array will be `(20, 3)`. Therefore, the output of the program will be: 

1
The array shape is (20, 3)

Output

Let's analyze the given Python code step-by-step. 1. **Importing NumPy**: The code starts by importing the NumPy library, which is often abbreviated as `np`. 2. **Creating an Array**: 

1
2
   array = np.zeros((10, 20, 30))
This line creates a 3-dimensional NumPy array filled with zeros. The shape of the array is `(10, 20, 30)`, meaning it has: - 10 layers (or "slices"), - 20 rows, and - 30 columns. 3. **Creating Index List**: 
1
2
   idxs = [1, 2, 3]
This line creates a list called `idxs` containing the integers 1, 2, and 3. This list will be used for advanced indexing. 4. **Accessing Array Elements**: 
1
2
   print("The array shape is", array[0, :, idxs].shape)
In this line, we access a specific slice of the `array`: - `array[0, :, idxs]`: - `0` specifies the first layer of the 3D array (the first "slice"). - `:` selects all rows in that slice. - `idxs` specifies the columns to select, which are the columns at indices 1, 2, and 3. The shape of the resulting array after this indexing operation will be: - The first axis (the selected layer) has a size of 1 (since we selected only `0`). - The second axis (all rows) has a size of 20. - The third axis (the selected columns) has a size of 3 (since we selected columns 1, 2, and 3). Therefore, the shape of `array[0, :, idxs]` will be `(20, 3)`. 5. **Output**: The final print statement will output the shape of the resulting array: 
1
2
   The array shape is (20, 3)
So, the complete output of the program will be: 
1
The array shape is (20, 3)

Output

Let's analyze the provided Python code step by step. 1. **Importing NumPy**: The code begins by importing the NumPy library, which is a popular library for numerical computing in Python. 2. **Creating a 3D array**: The line `array = np.zeros((10, 20, 30))` creates a 3D NumPy array filled with zeros. The shape of this array is `(10, 20, 30)`, meaning it has: - 10 layers (or pages), - 20 rows, - 30 columns. 3. **Defining index list**: The variable `idxs` is defined as a list containing the integers `[1, 2, 3]`. This list will be used to index the last dimension of the array. 4. **Indexing the array**: The expression `array[0, :, idxs]` is where most of the action happens: - `0` selects the first layer (or page) of the array (the first index of the first dimension). - `:` selects all rows (the second dimension). - `idxs` selects specific columns from the last dimension (the third dimension) based on the indices provided in the `idxs` list. Since `idxs` contains `[1, 2, 3]`, we are selecting columns 1, 2, and 3 from all 20 rows in the first layer of the array. 5. **Shape of the resulting array**: The shape of the resulting array from the indexing operation is determined as follows: - We have selected 1 layer (the first index is fixed at 0), - We have selected all 20 rows (which remains the same), - We have selected 3 columns (from the indices 1, 2, and 3). Therefore, the resulting shape will be `(20, 3)`. 6. **Printing the shape**: Finally, the code prints the shape of the resulting array using: 

1
2
   print("The array shape is", array[0, :, idxs].shape)
Given all the above points, the output of the program will be: 
1
The array shape is (20, 3)
