Using python programming please generate a 10 x 10 array y of integers from 100 (inclusive) to 1 (inclusive) in a way that entails the first row having integers from 100 to 91, the second row from 90 to 81, and so on and so forth. Note that the order of values matters. Next please appoint all the values that are in the first 3 rows and the last 7 columns of x and save the resulting array in x_top_right. Select all the values that are in the last 7 rows and the first 3 columns of y and save the resulting array in y_bottom_left.
