Tic Tac Toe AI Bugs plz help me fix it - python-3.x

Question

I am trying to create a Tic-Tac-Toe AI that will never lose. My code works sometimes but it does not work other times. Sometimes it will find the best move and print it out correctly but other times it will just fail. For example, once the AI takes the center if you press nine and take the top right corner then the AI will take a top left corner. Then if you take the bottom right corner the AI takes the middle left tile and then if you take the middle right tile then you will win. I wanted the AI to take the middle right to stop you from winning. I am a beginner programmer so please excuse me if the code is not written in the most optimal way. Why is that? Also can you please elaborate your explanation so I can understand what is wrong? Here is the code:
the_board = {'7': ' ', '8': ' ', '9': ' ',
'4': ' ', '5': ' ', '6': ' ',
'1': ' ', '2': ' ', '3': ' '}
def print_board(board):
print(board['7'] + '|' + board['8'] + '|' + board['9'])
print('-+-+-')
print(board['4'] + '|' + board['5'] + '|' + board['6'])
print('-+-+-')
print(board['1'] + '|' + board['2'] + '|' + board['3'])
def check_for_win(current_state_of_the_board, player_sign):
if current_state_of_the_board["7"] == current_state_of_the_board["8"] == current_state_of_the_board["9"] == player_sign:
return "Victory"
