To use the `numpy.argsort()` method in descending order in Python, negate the array before calling `argsort()`.
To use np.argsort in descending order in Python, first apply np.argsort to our array, and then either invert the result using array slicing ([::-1]) or negate the array before sorting. For inverting, sort the array using np.argsort and then reverse the resulting indices. For negating, ...
