Answer 2

A python program to implement a stack using a list data structure:

class Stack:

   def __init__(self):

       self.stack = []

   def push(self, item):

       self.stack.append(item)

   def pop(self):

       if len(self.stack) == 0:

           return None

       else:

           return self.stack.pop()

   def peek(self):

       if len(self.stack) == 0:

           return None

       else:

           return self.stack[-1]

   def is_empty(self):

       return len(self.stack) == 0

• You can use this stack by creating an instance of the class, for example:

s = Stack()

s.push(1)

s.push(2)

s.push(3)

print(s.pop()) # outputs 3

print(s.pop()) # outputs 2

print(s.pop()) # outputs 1
