Please write the functions in python, include explanation for each line of code and include a screenshot of the function to view correct indentation Define the function using the Stack ADT Don't define your own Stack class instead your code can make use of any the Stack ADT methods: Stack(), push(), pop(), peek(), size() and is_empty().

Write a function called get_top_of_stack(a_stack) which takes a Stack object as a parameter, and returns the value that is on the top of the stack. If the parameter stack is empty, the function should return None

Test	Result
s = Stack() s.push(100) s.push(101) s.push(102) s.push(103) s.push(104) x = get_top_of_stack(s) print(x) print(s)	104 Stack: [100, 101, 102, 103, 104]
s = Stack() x = get_top_of_stack(s) print(x)	None
