python - 在python中用逗号分隔数字

问题描述

我正在构建一个数独游戏，我找到了一个可以为我提供 100 万个预生成游戏的网站。我下载了文件 (CSV) 并想准备它以供前端使用。每场比赛都是81个数字

我很想创建包含所有谜题的 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中成功完成的

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)

这是我目前在puzzles.json 中的输出

请问有什么建议吗？谢谢

解决方案

您可以使用列表推导将字符串分解为数字

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

然后你通过使用另一个列表理解将其分解为长度为 9 的块

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

如果您希望输出是整数而不是字符串，int(number) for number in str(sudoku)请在列表推导中使用
