How do you switch a negative to a positive and a postive to a negative in a list?

Question

I want to make a function to do this. For example [1,-3, 5] would become [-1, 3, -5]

Can also use numpy and do `np.array(values) * -1` or `-np.array(values)` — rafaelc, Aug 20 '18 at 00:21

Just use list comprehension:

a = [1, -3, 5]
negative = [-x for x in a]
print(negative)

Output:

[-1, 3, -5]
