Python Numpy MiniProjects : Implementation of Tic-Tac-Toe game

-

     Tic-Tac-Toe is a thinking game between two opponents. Each one has a symbol ‘o’ or ‘x’. The first person who built the three consecutive rows or columns or diagonals win the game. Opponent player will keep on move their symbols to make sure that opposite person should not make the three consecutive moves.

Let us implement it using Numpy Arrays

Implementation:

import numpy as np1

# First a 3x3 game board is created

board = np1.full((3, 3), "-")

def display_board():

    print("\nCurrent Board:")

    print(board)

def check_winner(player):

    # Check for rows to find three consecutive moves

    for row in board:

        if np1.all(row == player):

            return True

    # Check columns for three consecutive columns

    for col in board.T:

        if np1.all(col == player):

            return True

    # Check diagonals for three consecutive elements

    if np1.all(np1.diag(board) == player):

        return True

    if np1.all(np1.diag(np1.fliplr(board)) == player):

        return True

    return False

def board_full():

    return np1.all(board != "-")

# Players

players = ["X", "O"]

turn = 0

while True:

    display_board()

    player = players[turn % 2]

    print(f"\nPlayer {player}'s Turn")

    row = int(input("Enter row (0-2): "))

    col = int(input("Enter column (0-2): "))

    # Validate move

    if row not in range(3) or col not in range(3):

        print("Invalid position! Try again.")

        continue

    if board[row, col] != "-":

        print("Position already occupied! Try again.")

        continue

    board[row, col] = player

    # Check winner

    if check_winner(player):

        display_board()

        print(f"\n🎉 Player {player} wins!")

        break

    # Check draw

    if board_full():

        display_board()

        print("\n🤝 It's a Draw!")

        break

    turn += 1

Output:

Current Board:

[['-' '-' '-']

 ['-' '-' '-']

 ['-' '-' '-']]

Player X's Turn

Enter row (0-2): 1

Enter column (0-2): 0

Current Board:

[['-' '-' '-']

 ['X' '-' '-']

 ['-' '-' '-']]

Player O's Turn

Enter row (0-2): 0

Enter column (0-2): 0

Current Board:

[['O' '-' '-']

 ['X' '-' '-']

 ['-' '-' '-']]

Player X's Turn

Enter row (0-2): 1

Enter column (0-2): 1

Current Board:

[['O' '-' '-']

 ['X' 'X' '-']

 ['-' '-' '-']]

Player O's Turn

Enter row (0-2): 1

Enter column (0-2): 2

Current Board:

[['O' '-' '-']

 ['X' 'X' 'O']

 ['-' '-' '-']]

Player X's Turn

Enter row (0-2): 0

Enter column (0-2): 1

Current Board:

[['O' 'X' '-']

 ['X' 'X' 'O']

 ['-' '-' '-']]

Player O's Turn

Enter row (0-2): 2

Enter column (0-2): 1

Current Board:

[['O' 'X' '-']

 ['X' 'X' 'O']

 ['-' 'O' '-']]

Player X's Turn

Enter row (0-2): 0

Enter column (0-2): 2

Current Board:

[['O' 'X' 'X']

 ['X' 'X' 'O']

 ['-' 'O' '-']]

 

Player O's Turn

Enter row (0-2): 2

Enter column (0-2): 0

Current Board:

[['O' 'X' 'X']

 ['X' 'X' 'O']

 ['O' 'O' '-']]

Player X's Turn

Enter row (0-2): 2

Enter column (0-2): 2

Current Board:

[['O' 'X' 'X']

 ['X' 'X' 'O']

 ['O' 'O' 'X']]

🤝 It's a Draw!

This is the way of implementing Tic-Tac-Toe in Numpy arrays using Python. Hope, you understood the code. Keep Coding!!!

XML  is    e X tensible M arkup L anguage which is used to create used defined tags.  It has Elements  ( <STUDENT>) Attributes (<STUDENT id="21it21">) To create a XML file, create three files 1 ->  XML file (used to declare the user defined tags) 2 ->  DTD file (used to define the user defined tags) 3 ->  HTML file(used to display the xml file as web page) create these three files using any editor like notepad.  Student.Xml <?xml version="1.0"?> <!DOCTYPE STUDENTS SYSTEM "E:\XML1\STUDENT.dtd"> <STUDENTS>  <STUDENT>  <STUDENTDATA>     <NAME> SUTHA </NAME>     <ID>  2007IT51 </ID>     <AGE> 20 </AGE>     <ADDRESS> 12, SATHY ROAD , GOBI </ADDRESS>   </STUDENTDATA> </STUDENT> </STUDENTS> Student.dtd <?xml version="1.0"?> <!ELEMENT STU...

Employee record management in C

               Let us create a employee record management in C. A employee record has name, id and salary. The operations are adding the details, search an employee, delete a record and display the employee records. Program implementation: #include <stdio.h> #include <stdlib.h> #include <string.h> #define MAX 100 struct Employee {     int e_id;     char e_name[50];     float e_salary; }; struct Employee emp[MAX]; int count = 0; void addEmployee() {     printf("\nEnter the Employee id: ");     scanf("%d", &emp[count].e_id);     printf("Enter the Employee Name: ");     scanf(" %[^\n]", emp[count].e_name);     printf("Enter the salary: ");     scanf("%f", &emp[count].e_salary);     count++;     printf("Employee details ar...

Datatypes and Variables in java script

-
Image
Datatypes are used to hold the values of variables. JavaScript has two types of datatypes. ·        Primitive data types ·        Non-primitive data types Java script is a dynamic type. It is not important to mention the datatype earlier. Use “var” for variable. Primitive data types: Javascript has 5 primitive data types. They are listed below. Boolean : it represents zero or one value. Number : it represents numbers. String :it represents sequence of characters. Null : it represents no value. Undefined: if you want to define the value later, use this data type. Non- primitive data types: Javascript has 3 different types of non-primitive data types. They are given below. Array : It has a list of similar values Object : it is a instance of a class. Regexp : It is for Regular Expressions.   Variables:   Variables are so important for any language. It specifies the value. In javascri...
