In this exercise we wil encapsulate the selve ip function from scipy into our own salve method in Dooel. This is yet another concept from the four pillars of object-oriented design The result will also be encapsulated in a NuedTuple, which for the code is called Result implement a NasedTuple named cocesult in ode.py with the fields tine and solution which should both benumpy amays. See Named Tule for more info about sedaple Hint-Named Tuple You can create a Named Tuple using the following code inport numpy as p from typing import Neduple class 00EResult (NamedTuple): tine: np.ndarray solutions ne nderray Note that some of the subclasses of cocmodel will use a different result class than ODEResult. Therefore, the model class should be instantiated in a private method _create_result Given that solation is the output of add the method below to ocemodel. Here create_result(self, salation): return Resultitime-solution.. solution-solution.y The method will be overwritten in some subclasses of comode, but this is not necessary for ExponentialDecay which simply uses consult. For solving the ODE, write a method with the following signature: def solveiself, np.ndarray, T: flost, dt: float, method: str=" the first argument (u) is the initial conditions), Tis the end time and at is the time step you should start at time) The solve method should return the encapsulated results using the create result method. Also, when calling solve tv, supply the keyword
