Hello I need help on a Python Programming Lab

Below, I will post the starter code:

This must be done within the classes and fucntions given in the starter code. You cannot delete or add any classes or functions

Goal: [10 pts] In the video lectures, we discussed the abstract data type Stack. A stack is a collection of items where items are added to and removed from the top (LIFO). Use the Node class (an object with a data field and a pointer to the next element) to implement the stack data structure with the following operations: Stack) creates a new stack that is empty. It needs no parameters and returns nothing * push(item) adds a new Node with value-item to the top of the stack. It needs the item and * pop) removes the top Node from the stack. It needs no parameters and returns the value * peek) returns the value of the top Node from the stack but does not remove it. It needs no isEmpty() tests to see whether the stack is empty. It needs no parameters and returns a * size) returns the number of items on the stack. It needs no parameters and returns an returns nothing of the Node removed from the stack. Modifies the stack. parameters. The stack is not modified. boolean value. nteger. EXAMPLE >>> x=Stack ( ) >>> x.pop () Stack is empty' >>x.push (2) >>> x.push (4) >>> x.push (6) Top: Node (6) Stack: 4
