Python数独谜题求解器无法正确显示谜题

Question

我试图写一个Sudoku难题求解器，到目前为止，我一直在试图让它显示难题。到目前为止，这是我的代码：class Cell:'''A cell for the soduku game.'''def __init__(self):    #This is our constructor    self.__done = False #We are not finished at the start    self.__answer = (1,2,3,4,5,6,7,8,9) #Here is the tuple containing all of our possibilities    self.__setnum = 8 #This will be used later when we set the number.def __str__(self):    '''This formats what the cell returns.'''    answer = 'This cell can be: '    answer += str(self.__answer) #This pulls our answer from our tuple    return answerdef get_possible(self):    '''This tells us what our possibilities exist.'''    answer = ()    return self.__answerdef is_done(self):    '''Does a simple check on a variable to determine if we are done.'''    return self.__donedef remove(self, number):    '''Removes a possibility from the possibility tuple.'''    if number == 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9: #Checks if we have a valid answer        temp = list(self.__answer) #Here is the secret: We change the tuple to a list, which we can easily modify, and than turn it back.        temp.remove(number)        self.__answer = tuple(temp)def set_number(self, number):    '''Removes all but one possibility from the possibility tuple. Also sets "__done" to true.'''    answer = 8    for num in self.__answer:        if num == number:            answer = number #Checks if the number is in the tuple, and than sets that value as the tuple, which becomes an integer.    self.__answer = answer    self.__done = True    return self.__answer尝试打印时，会出现两条垂直的管道（|）。有人可以告诉我我在做什么错吗？

Answer 1

这是错误的（它将始终为True）

if number == 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9:

采用

if 1 <= number <= 9:

这也是错的

for char in self.__file:

    if char == '.':

        self.__puzzle += ' '

    else:

        self.__puzzle += char

遍历文件会产生行而不是字符。

我建议您以较小的部分编写和测试代码。print在其中放一些s，以确保代码正在执行您期望的操作。
