Question

我正在构建一个数独游戏，我发现一个site可以为我提供100万个预生成的游戏。我下载了文件（CSV），并希望为前端使用做准备。每个游戏都有81个数字，例如

346179258187523964529648371965832417472916835813754629798261543631485792254397186
974183652651274389283596714129835476746912538835647921568329147317468295492751863
563472198219386754847195623472638519951247386638519472795864231324951867186723945

我想创建所有拼图的JS或JSON文件，以便将其导入我的代码中。这是每个游戏（线）的理想结果。

    [
         [5, 3, 4, 6, 7, 8, 9, 1, 2],
         [6, 7, 2, 1, 9, 5, 3, 4, 8],
         [1, 9, 8, 3, 4, 2, 5, 6, 7],
         [8, 5, 9, 7, 6, 1, 4, 2, 3],
         [4, 2, 6, 8, 5, 3, 7, 9, 1],
         [7, 1, 3, 9, 2, 4, 8, 5, 6],
         [9, 6, 1, 5, 3, 7, 2, 8, 4],
         [2, 8, 7, 4, 1, 9, 6, 3, 5],
         [3, 4, 5, 2, 8, 6, 1, 7, 9]
     ]

这是我在python中设法完成的事情

import csv
import json
holder = []
rows = []
def divide_chunks(l, n): 
    # looping till length l 
    for i in range(0, len(l), n):  
        yield l[i:i + n] 

with open('sudoku.csv', newline='') as csvfile:
    counter = 0
    n = 9
    s=','
    reader = csv.DictReader(csvfile)
    for row in reader:
        if counter > 10:
            break
        print(row['solutions'])
        print(len(row['solutions']))    
        test = [int(str(row['solutions']))]
        #chunk = divide_chunks(test, n)
        # for val in enumerate(chunk):
        #     val = [val]
        #     # for index,item in enumerate(val):
        #     #     item[index] = item+s
        #     # print(val)

        holder.append(test)
        counter +=1


print(holder)

with open('puzzles.json', 'w') as outputfile:
    json.dump(holder,outputfile)

这是到目前为止我在puzzles.json中的输出

有什么建议吗？谢谢

Answer 1

您可以通过列表理解将字符串分成数字

sudoku = 346179258187523964529648371965832417472916835813754629798261543631485792254397186
sudoku_list = [number for number in str(sudoku)]

然后您通过使用另一个列表理解将其分成9个长度的块

sudoku_final = [sudoku_list[9*i:9*i+9] for i in range(9)]

如果您希望输出为整数而不是字符串，请在列表理解中使用int(number) for number in str(sudoku)

Answer 2

使用Python，您可以将所有数字转换为字符串，然后将其转换回列表，如下所示：

tuple(map(int, str(x)))  # x is the 81 digit number.

这样，您可以将81位数字的列表分成9x9的网格，如下所示（迭代9的倍数并取下9个数字）：

[x[i: i + 9] for i in range(0, 81, 9)]

在python中用逗号分隔数字
