INTRODUCTION
This project, “Tic Tac Toe” in Python, demonstrates the application of
programming concepts learned in Grade 11. The game of Tic Tac Toe,
also known as Noughts and Crosses, is a simple yet engaging two-player
game where participants alternately mark spaces on a 3x3 grid with their
respective symbols (X and O). The goal is to align three of their symbols
horizontally, vertically, or diagonally to win the game.
The purpose of this project is to implement the rules and logic of Tic
Tac Toe using Python. It involves the use of core programming concepts
such as:
• Conditional Statements: To check game states and declare
results.
• Loops: For managing turns and validating moves.
• Functions: To modularize the code for clarity and reusability.
• Lists: To represent the game board and manage player moves.
This project is designed to enhance problem-solving skills, logical
thinking, and understanding of Python programming fundamentals. By
the end of the project, the user will have an interactive and fully
functional game of Tic Tac Toe that can be played in the console.
ACKNOWLEGMENT
I, Yashas.M, express my heartfelt gratitude to everyone who supported
and guided me in completing this project, Tic Tac Toe in Python
I am immensely thankful to Mrs. Thejaswini, my Computer Science
teacher, for her valuable guidance, encouragement, and insights
throughout the development of this project. Her dedication and teaching
have been instrumental in enhancing my understanding of programming
concepts.
I also extend my sincere thanks to our respected Principal, Mrs. Priya
Simon George, for providing a supportive and inspiring academic
environment that fosters learning and innovation.
Finally, I would like to thank my parents, classmates, and friends for
their continuous motivation and support in completing this project
successfully.
Thank you all for making this journey both enriching and memorable.
