Hello! We are given the project specifications for a python class. I have implemented all the previous class methods, yet cannot figure out this method/local function combination. Could you please explain / code how the local functions are meant to be implemented? Thank you very much.

sim(tfinal, nsteps): i.tfinal . output: out := t, odeint(ode, (s.cm_x(), s.cm_y(), Va, Vy],t) where t [i: Ni (0..nsteps 1] nsteps-1 # for the sequence of t values the values should be in the natural ascending order for the i values exception: none Local Functions ode : (seq [4] of R) XR seq [4] of R ode(w,t) = [w[2], w[3], Fr(t)/s.mass(), Fy(t)/s.mass()] sim(tfinal, nsteps): i.tfinal . output: out := t, odeint(ode, (s.cm_x(), s.cm_y(), Va, Vy],t) where t [i: Ni (0..nsteps 1] nsteps-1 # for the sequence of t values the values should be in the natural ascending order for the i values exception: none Local Functions ode : (seq [4] of R) XR seq [4] of R ode(w,t) = [w[2], w[3], Fr(t)/s.mass(), Fy(t)/s.mass()]
