Stack Implementation Using Python

How stack works and logic

If we imagine a stack horizontally then...
Element in stack is inserted in the same way we append an element to an array. So this logic could be used for the push function of our stack.
Element is popped from the end of the stack so we have a direct pop() function which can be implemented in the pop function for this. pop() removes the first element from a list so we use pop(-1) to remove the last element.

This was a question from GeeksForGeeks Practice

Ex: push(1), push(2), push(3), pop()
[1] [1,2] [1,2,3] [1,2]

Code

`class MyStack:

def __init__(self):
    self.arr=[]

#Function to push an integer into the stack.
def push(self,data):
    #add code here
    self.arr.append(data)

#Function to remove an item from top of the stack.
def pop(self):
    #add code here
    if len(self.arr) > 0:
        popped = self.arr.pop(-1)
        return popped
    else:
        return -1`

My First Python Game

Jai Irkal — Wed, 28 Jul 2021 17:17:12 +0000

Hello coders and developers!
This is the first game I have made a Stone-Paper-Scissors-Game using Python. I have not used any library like PyGame. I have developed it using the random module in the Python Standard Library.

Python Standard Library

Python Standard Library is a set of modules which are included with every Python installation.
One of them used in this game is random module.

Random Module

Important functions in the random module are randint() and choice().
In this game I have used the choice() function.
1. randint() ---> This function returns any random integer within the given arguments.
2. choice() ---> This function returns a random value from a tuple or a list.

Talking about my game, it takes a user input for stone paper or scissors and the computer chooses a random value i.e. stone paper or scissors. You know the rest rules I think 😉
So this was the simple logic I used.

The link for all the files is here. I have also converted the game into a module so that it looks clean 😁

Happy Coding! 👨‍💻👩‍💻

Stone-Paper-Scissors-Game

A simple stone paper scissors game like we used to play when we all were kids. Simple Python is being used using the random module from Standard Python Library.

I have also converted the game into module for simple use...

Python Learning Sources

I have been using a lot of resources to learn Python Programming. As I myself am still learning, I wanted to share some resources I personally felt really helpful.

Book I would Recommend

I won't prefer reading a book to learn programming but this book has impressed me a lot!
I am referring to the book named 'Python Crash Course: A Hands On Project Based Introduction to Programming' by Eric Matthes. This book has been really helpful. Do give it a read and also practice the exercise questions.

After you are thorough with the book then you can go to W3Schools and solve those exercises(those are pretty easy questions). This will probably give you more confidence 👍

Finally you have to solve problems from HackerRank. These questions might be a bit complex and tricky but more you try the more you learn. I myself had to do much to solve the problems. But no pain no gain!

Useful YouTube videos related to python programming can be accessed through these links:

If you guys found this post helpful then save it so you can refer anytime 😊.
Happy Coding! 👨‍💻 👩‍💻
