Look at your current code for flip

def flip(board, row, col, player, playerOpposite):
   while(row<len(board)-2 or col!=0):
      row+=1
      col-=1
      print(row,col)
      if (board[row][col]==playerOpposite):
        board[row][col]=player

Your while loop will continue as long as col is not zero. Given that col starts negative and you continue to subtract one from it, it will always be non-zero and it is an infinite loop.
