Question
What values does the variable out take if the following lines of code are run?45123out X=np.array([[1,0,1],[2,2,2]]) out=X[0,1:3]0 / 1 pointarray([2,2])array([1,0,1])array([0,1])
Solution
The variable 'out' will take the values of the elements at index 1 and 2 of the first row of the array 'X'. In Python, indexing starts from 0 and the range is exclusive of the end index. So, 'X[0,1:3]' will select elements from the first row (0 index) starting from column index 1 up to, but not including, column index 3.
The array 'X' is defined as follows:
X = np.array([[1,0,1],[2,2,2]])
So, the first row is [1,0,1]. The elements at index 1 and 2 of this row are 0 and 1 respectively.
Therefore, the variable 'out' will take the value array([0,1]).
