所以我有兩個用戶定義的python類，如下所示class cell(object):def __init__(self,id,x_cor,y_cor,width = cell_size,height = cell_size ,color = lightblue ):    self.id = id    self.x_cor = x_cor    self.y_cor = y_cor    self.width = width    self.height = height    self.color = colorclass edge(object):def __init__(self,pos, x_cor,y_cor,state,color = lightgreen):    global border_size    global cell_size    self.pos = pos    self.x_cor = x_cor    self.y_cor = y_cor    self.state = state    self.color = color    if self.state == "H":        self.width = cell_size+(border_size)*2        self.height = border_size        self.x_lower_bound = self.x_cor + border_size        self.x_upper_bound = self.x_cor +border_size+ cell_size        self.y_lower_bound = self.y_cor        self.y_upper_bound = self.y_cor + border_size    elif self.state == "V":        self.width = border_size        self.height = cell_size+(border_size*2)        self.x_lower_bound = self.x_cor        self.x_upper_bound = self.x_cor + border_size        self.y_lower_bound = self.y_cor + border_size        self.y_upper_bound = self.y_cor + border_size + cell_size現在我有一個名為單元格的2-D列表 它被定義并看起來像這樣 點擊我。它有點混亂，但你可以看到它是一個16×16的矩陣，存儲一個對象od單元格，如上定義。不，我想將此2-D數組存儲在json文件中，這就是我正在做的事情json_data = []json_data.append(cells)with open("default.json" , "w") as f:    json.dump(json_data,f,indent = 2)
