Chapter-14 Question 1 Which parameter specifies the index at which to insert elements? arr obj values axis Question 2 What is the syntax for inserting elements into an ndarray at a specific index? np.insert(arr, obj, values, axis=None). np.add(arr, obj, values). np.append(arr, obj, values). np.update(arr, obj, values, axis=None). Question 3 What happens if you insert elements into an ndarray at an index that already contains a value? The existing value is replaced. A new element is inserted before the existing one. The existing value is shifted to the right. An error is raised. Question 4 Which of the following is a valid way to insert a row into a 2D ndarray? np.insert(arr, 0, [1, 2, 3], axis=0). np.insert(arr, 1, [1, 2, 3], axis=1). np.insert(arr, 0, [1, 2, 3]). np.insert(arr, 0, [1, 2, 3], axis=-1). Question 5 How can you insert a column into a 2D ndarray? Use np.hstack Use np.insert(arr, 0, values, axis=1). Use np.vstack Use np.append(arr, values, axis=1). Question 6 Which axis parameter value should be used to insert elements along the rows in a 2D ndarray? 0 1 -1 None Question 7 What is the default value of the axis parameter in the np.insert function? 0 1 -1 None Question 8 Which numpy function is used to insert elements into an ndarray? add Insert append update Question 9 In numpy, how can you insert elements into an ndarray without modifying the original array? Use the copy method. Use the resize method. Use the np.insert function with a copy of the array. Use the np.copy function. Question 10 In numpy, how can you insert multiple elements at once into an ndarray? Use multiple np.insert calls. Use np.concatenate. Use np.insert with a list of indices. Use np.insert with a list of values. Name Email Phone
