2. Car Class Write a class named car that has the following data attributes: year_model (for the car's year model) _make (for the make of the car) speed (for the car's current speed) The car class should have aninit. method that accepts the car's year model and make as arguments. These values should be assigned to the object's _year_model and make data attributes. It should also assign 0 to the speed data attribute. The class should also have the following methods: accelerate The jaccelerate method should add 5 to the speed data attribute each time it is called. brake The brake method should subtract 5 from the speed data attribute each time it is called. get speed The get speed method should return the current speed. Next, design a program that creates a Car object then calls the accelerate method five times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method five times. After each call to the brake method, get the current speed of the car and display it.

Dictionaries are mutable in python. True or false?

I've been struggling with understanding a question in my Python programming homework.I'm asked to construct a program that asks the user to enter a distance in kilometers, and then convert that distance into miles with the formula miles - kilometers X 0.6214. I'm not sure where to proceed since I'm getting several wildly different answers from different sources.
