import numpy as np
x = np.arange(21)
print("Original vector:")
print(x)
print("After changing the sign of the numbers in the range from 9 to 15:")
x[(x >= 9) & (x <= 15)] *= -1
print(x)Sample Output:
Original vector: [ 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20] After changing the sign of the numbers in the range from 9 to 15: [ 0 1 2 3 4 5 6 7 8 -9 -10 -11 -12 -13 -14 -15 16 17 18 19 20]
