Interpolate parameter from csv data

[presvetli]

For Negative electrode OCP [V] I have some .csv data (x=sto, y=ocp). I want to skip function fitting for that data, if it is possible.
In some parameter function file, can I read csv data in X, Y list and use numpy to find interpolate parameter from table --> numpy.interp(sto, X, Y)?
sto: :class:pybamm.Symbol Electrode stochiometry

please use
pybamm.interpolant(x,y,sto)
