How do you determine (code) if the stack is empty?

Question

I am learning data structures and am currently working on stacks. I was wondering how you determine if the stack is empty?

from copy import deepcopy

class Stack:

    def __init__(self):
        """
        -------------------------------------------------------
        Initializes an is_empty stack. Data is stored in a Python list.
        Use: s = Stack()
        -------------------------------------------------------
        Returns:
            a new Stack object (Stack)
        -------------------------------------------------------
        """
        self._values = []

    def is_empty(self):
        """
        -------------------------------------------------------
        Determines if the stack is empty.
        Use: b = s.is_empty()
        -------------------------------------------------------
        Returns:
            True if the stack is empty, False otherwise
        -------------------------------------------------------
        """

        # Your code here

That's exactly what you're supposed to be working out, that's the whole point of the task. — jonrsharpe, May 19 '19 at 21:36

If self._values is an empty list, the stack is empty
