You are making a mistake while using brackets. Bracket around each of the conditions so that NumPy considers them as individual arrays.
targets = np.random.randint(0,10,(10,))
mask = (targets>=0) & (targets<=5) #<----------
print(mask)
targets[mask]
[ True False True False False True True True False True]
array([4, 1, 3, 1, 5, 3])
You can create some complex logic using multiple masks and then directly index an array with them. Example - XNOR can be written as ~(mask1 ^ mask2)
