Python Guided Project: Building Tic-Tac-Toe from Scratch

Explore building a Python tic-tac-toe game from scratch with an automatic setup where the CPU plays both sides using 1 and 2, a purely random, non-ai implementation for beginners.

Plan and implement Python tic-tac-toe with main function and four sub-functions: create an empty board, check spots, place 1s and 2s, and evaluate winner or tie, illustrating object oriented programming.

Import numpy and random to build an empty 3x3 tic-tac-toe board with a function named empty_board that returns a 3-by-3 zero matrix and uses sleep to pause briefly.

Implement functions to check for empty spots on a tic-tac-toe board and to place an x or o at a random available position, using numpy arrays and random.choice.

Explore implementing tic-tac-toe win and tie logic in Python by evaluating horizontal rows, vertical columns, and diagonals with dedicated functions and test cases.

evaluate tic-tac-toe diagonals using the diag winner function to verify primary and secondary diagonals for a winner and set up for combining the code.

Evaluate the tic-tac-toe board by checking rows, columns, and diagonals to determine a winner or a tie, using a winner variable to represent indecisive, player one, player two, or tie.

Create the tic-tac-toe main function, initialize an empty board and winner, print the board after each move with a delay, and evaluate the game to determine the winner.

Explore extending the tic-tac-toe project with a human versus CPU mode and an AI that uses breadth-first and depth-first search to improve and help the CPU learn to win.
