Function for the Normal Loss Function L(z) - Smelly - Jan-31-2019

I am pretty new to Python and my algorithm is working with the Normal loss function L(z)

L(z)=ϕ(z)−z(1−Φ(z))

I have "z" as an input and need "L(z)" as an output.

A table of that looks like this:

Does a package exist which provides a function to do so? What is the name of the package and function?

You can use SciPy package, it includes ϕ(z) and Φ(z) functions (normal probability density and its cumulative distribution function), so you can easily define
L(z) using them.
