How to Implement Stack Data Structure in Python

Submitted by razormist on Friday, December 5, 2025 - 23:36.

In this tutorial, we will learn how to program "How to Implement Stack Data Structure in Python." The objective is to apply the stack data structure. This tutorial will guide you step by step through methods for the stack data structure. By the end of this tutorial, you will have a solid understanding of how to implement this task effectively in Python, helping you strengthen your problem-solving abilities and improve your coding skills.

This topic is straightforward and easy to understand. Simply follow the instructions provided, and you will complete it with ease. The program will guide you step by step through the process of the stack data structure. So, let’s dive into the coding process!

Getting Started:

First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.

Creating Main Function

This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.
  1. class Stack:
  2.     def __init__(self):
  3.         self.items = []
  4.  
  5.     def is_empty(self):
  6.         return self.items == []
  7.  
  8.     def push(self, data):
  9.         self.items.append(data)
  10.  
  11.     def pop(self):
  12.         return self.items.pop()
  13.  
  14.  
  15. while True:
  16.     print("\n============ Implement Stack Data Structure ============\n")
  17.  
  18.     s = Stack()
  19.  
  20.     while True:
  21.         print('push <value>')
  22.         print('pop')
  23.         print('quit')
  24.  
  25.         do = input('What would you like to do? ').split()
  26.         operation = do[0].strip().lower()
  27.  
  28.         if operation == 'push':
  29.             if len(do) < 2:
  30.                 print("Please enter a value to push.")
  31.             else:
  32.                 s.push(int(do[1]))
  33.  
  34.         elif operation == 'pop':
  35.             if s.is_empty():
  36.                 print('Stack is empty.')
  37.             else:
  38.                 print('Popped value:', s.pop())
  39.  
  40.         elif operation == 'quit':
  41.             break
  42.        
  43.         else:
  44.             print("Invalid operation.")
  45.  
  46.     # Try again?
  47.     opt = input("\nDo you want to try again? (yes/no): ").strip().lower()
  48.     if opt == "no":
  49.         print("Exiting program...")
  50.         break
  51.     elif opt != "yes":
  52.         print("Invalid choice. Exiting program...")
  53.         break

This program implements a basic stack data structure in Python using a class. It allows the user to interactively push values onto the stack, pop values from it, and quit the current session. The stack operations are managed with a `Stack` class that maintains an internal list and provides methods to check if empty, push, and pop elements. The program repeatedly prompts the user to perform stack operations or restart with a new stack.

Output:

There you have it we successfully created How to Implement Stack Data Structure in Python. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
