Python Sudoku拼圖9 x 9 Checker

Question

while True: 
    try: 
     file = input("Enter a filename: ") 
     fi = open(file, "r") 
     infile = fi.read() 
     grid = [list (i) for i in infile.split()] #Puts the sudoku puzzle into a list in  order to check that the total number is valid 
     check = len(grid) 
     print("The total number in this puzzle is:",check) #Counts the amount of numbers in the sudoku puzzle 
     break 
    except FileNotFoundError: 
     print ("The inputted file does not exist") 

def check(infile): 
    count = 0 
    for j in range (0,9): 
     for n in range(0,9): 
      if infile[j].count(infile[j][n]) <= 1: 
       count = count + 0 
      else: 
       count = count + 1 

這是我當前的一個數獨檢查器的代碼，有人請告訴我它有什麼問題，因爲我試圖找出列中的所有數字是否在1和9

您從未明確地在此代碼中調用函數check。
