We can implement a stack using a list in Python , as a list is a dynamic data structure that can grow or shrink as needed. 

We can use the built-in methods of list, such as append and pop , to perform push and pop operations on the stack. 

We can also use the len function to get the size of the stack, and check if it is empty or full.

Here is an example of how to implement a stack using a list in Python:

  • create an empty list to store the stack elements

stack = []

  • define a function to push an element to the stack

def push(element): 

# append the element to the end of the list 


# print a message to indicate successful operation 

print(element, “pushed to stack”)

  • define a function to pop an element from the stack

def pop(): 

# check if the stack is empty 

if len(stack) == 0: 

# print a message to indicate error 

print(“Stack is empty”) 

# return None 

return None 


# pop and return the last element of the list 

element = stack.pop() 

# print a message to indicate successful operation 

print(element, “popped from stack”) 

# return the element 

return element

  • test the functions

push(10) # 10 pushed to stack 

push(20) # 20 pushed to stack 

push(30) # 30 pushed to stack 

pop() # 30 popped from stack 

pop() # 20 popped from stack 

pop() # 10 popped from stack 

pop() # Stack is empty
