print_board() function as the name says just helps in printing the current tic-tac-toe board.
player_move() function is the most important function in this tic-tac-toe game. This function takes the position as input from the user and fills that position in the board with the symbol of that player.
is_victory() function just checks if any of the two players have won or not.
is_draw() function checks if the game is drawn or not.
And then comes our main while loop which keeps the game going.
This program will stop only when either one player has won or the game is drawn.
