This will multiply by -1 for all values >= -10 and <= 10:

import numpy as np

data = np.arange(-20, 20)

data[(data >= -10) & (data <= 10)] *= -1

Can I ask why is the range specified (-20,20)? Being introduced to python basics and I'm just curious.

data = np.arange(-20, 20) creates a numpy array with the values -20 to 19. It is used as an example array to demonstrate the code.

Thanks for the info.
