Question
Example Array:arr =np.array([[1,2,3],[4,5,6],[7,8,9],[10,11,12]])Use the example array 'arr' to answer the following question:To select [4,5,6] from arr, we do _____.
Solution 1
To select [4,5,6] from arr, we do arr[1]. This is because in Python, array indexing starts from 0. So, arr[1] will give us the second row of the array.
Solution 2
To select [4,5,6] from arr, we do arr[1]. This is because in Python, array indexing starts from 0. So, arr[1] will give us the second row of the array.
