Question

我正在尝试将包含所有Magic the Gathering卡信息的JSON文件解析为平面csv文件。只是尝试在操作具有不同数据类型的数据集时练习 - 可以在此处找到源json文件（单击“All Sets”以下载JSON文件）：https://mtgjson.com/

可以在上述网站的文档选项卡中找到其他文档（即上述JSON文件中的所有字段）。

JSON文件的结构方式是> 200套，每套都有很多卡。我有下面的代码，它成功地将给定集合中每张卡片的所有必要卡级别信息（如法术力费用，卡片名称，卡片颜色等）写入CSV文件。但是，我还要向CSV写出信息，这是一个高于卡级别信息的级别 - 即设置级别信息。这些是“名称”，“代码”，......“助推器”之类的内容，您可以在以下屏幕截图中看到：https://imgur.com/a/olNvr。理想情况下，任何设置级别信息都将是CSV文件中的前几列，然后是卡级别信息。基本上是“平面”类型的CSV文件。

with open('AllSets.json', encoding = 'utf8') as f:
    json_data = json.load(f)

    header = ['id', 'layout', 'name', 'names', 'manaCost', 'cmc', 'colors', 'colorIdentity', 'type', 'superTypes', 'types', 'subtypes', 'rarity', 'text', 'flavor', 'artist', 'number', 'power', 'toughness', 'loyalty', 'multiverseid', 'variations', 'imageName', 'watermark', 'border', 'timeshifted', 'hand', 'life', 'reserved', 'releaseDate', 'starter', 'mciNumber']

    # create the csv writer object
    csvwriter = csv.DictWriter(open('testData.csv', 'w', newline='', encoding='utf-8'), fieldnames = header, extrasaction='ignore')

    csvwriter.writeheader()

    for set in sets:

        set_data = json_data[set]['cards']

        for card in set_data:

            csvwriter.writerow(card)

我认为在for card in set_data循环中我们需要能够逐行将设置级别信息写入CSV文件的代码。我为集合的特定代码字段尝试了csvwriter.writerow(set['code'])之类的内容，但不幸的是，这会产生TypeError: string indices must be integers错误。非常感谢任何建议！
