How to Calculate NPV?

I am using Spyder Python 2.7. I'm running this sample code.
import scipy as sp
cashflows=[50,40,20,10,50]
npv=sp.npv(0.1,cashflows)
round(npv,2)
Now, I'm trying to get the NPV, and I don't see any obvious way to get it.
The author of the book that I'm reading gets 144.56. I think that's wrong, but I don't know for sure, as Python won't do any calculation at all. It's easy to enter code and run it, but I can't tell how to get Python to actually DO the calculation.
Any idea what I'm doing wrong?
