【问题描述】：

[{"Name": "Luke Skywalker", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Darth Vader", "Affiliation": "Sith", "Allegiance": ""}, {"Name": "Obi-Wan Kenobi", "Affiliation": "Jedi", "Allegiance": "TO THE REPUBLIC, TO DEMOCRACY!"}, {"Name": "Anakin Skywalker", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Yoda", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Palpatine", "Affiliation": "Sith", "Allegiance": ""}, {"Name": "Qui-Gon Jinn", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Jar Jar Binks", "Affiliation": "N/A", "Allegiance": "Possible Sith"}, {"Name": "Darth Maul", "Affiliation": "Sith", "Allegiance": ""}, {"Name": "Mace Windu", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Ki-Adi-Mundi", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Kit Fisto", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Eeth Koth", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Plo Koon", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Dooku", "Affiliation": "Sith", "Allegiance": ""}]

上面的输出是我用代码得到的：

    data = []
    with open('starwrs.csv') as f:
        for row in csv.DictReader(f):
            data.append(row)

    json_data = json.dumps(data)
    return json_data

但是我如何得到它，使它看起来像实际的 json 数据，比如直接在彼此下面等，而不是我得到的字符串

[{"Name": "Luke Skywalker", "Affiliation": "Jedi", "Allegiance": ""}, 
{"Name": "Darth Vader", "Affiliation": "Sith", "Allegiance": ""}

【解决方案1】：

使用 json.dumps(json_object, indent=2)...

import json
json_data='[{"Name": "Luke Skywalker", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Darth Vader", "Affiliation": "Sith", "Allegiance": ""}, {"Name": "Obi-Wan Kenobi", "Affiliation": "Jedi", "Allegiance": "TO THE REPUBLIC, TO DEMOCRACY!"}, {"Name": "Anakin Skywalker", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Yoda", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Palpatine", "Affiliation": "Sith", "Allegiance": ""}, {"Name": "Qui-Gon Jinn", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Jar Jar Binks", "Affiliation": "N/A", "Allegiance": "Possible Sith"}, {"Name": "Darth Maul", "Affiliation": "Sith", "Allegiance": ""}, {"Name": "Mace Windu", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Ki-Adi-Mundi", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Kit Fisto", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Eeth Koth", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Plo Koon", "Affiliation": "Jedi", "Allegiance": ""}, {"Name": "Dooku", "Affiliation": "Sith", "Allegiance": ""}]'
json_object = json.loads(json_data)
json_formatted_str = json.dumps(json_object, indent=2)
print(json_formatted_str)

我猜你想漂亮地打印 json。如果是这种情况，请使用此

json_data = json.dumps(data, indent=4)
print(json_data)

json.dumps 中的缩进有助于创建使 json 看起来格式化的缩进

[
    {
        "Name": "Luke Skywalker",
        "Affiliation": "Jedi",
        "Allegiance": ""
    },
    {
        "Name": "Darth Vader",
        "Affiliation": "Sith",
        "Allegiance": ""
    },
    {
        "Name": "Obi-Wan Kenobi",
        "Affiliation": "Jedi",
        "Allegiance": "TO THE REPUBLIC, TO DEMOCRACY!"
    },
    {
        "Name": "Anakin Skywalker",
        "Affiliation": "Jedi",
        "Allegiance": ""
    },
    {
        "Name": "Yoda",
        "Affiliation": "Jedi",
        "Allegiance": ""
    },
    {
        "Name": "Palpatine",
        "Affiliation": "Sith",
        "Allegiance": ""
    },
    {
        "Name": "Qui-Gon Jinn",
        "Affiliation": "Jedi",
        "Allegiance": ""
    },
    {
        "Name": "Jar Jar Binks",
        "Affiliation": "N/A",
        "Allegiance": "Possible Sith"
    },
    {
        "Name": "Darth Maul",
        "Affiliation": "Sith",
        "Allegiance": ""
    },
    {
        "Name": "Mace Windu",
        "Affiliation": "Jedi",
        "Allegiance": ""
    },
    {
        "Name": "Ki-Adi-Mundi",
        "Affiliation": "Jedi",
        "Allegiance": ""
    },
    {
        "Name": "Kit Fisto",
        "Affiliation": "Jedi",
        "Allegiance": ""
    },
    {
        "Name": "Eeth Koth",
        "Affiliation": "Jedi",
        "Allegiance": ""
    },
    {
        "Name": "Plo Koon",
        "Affiliation": "Jedi",
        "Allegiance": ""
    },
    {
        "Name": "Dooku",
        "Affiliation": "Sith",
        "Allegiance": ""
    }
]

您好，谢谢您的回复！但是当我做这个改变时，它并没有改变我在 python 中所做的事情，因为我现在使用 python flask 运行它
数据将以字符串格式存储，不会有缩进。只有在打印时才会看到缩进。
你到底想做什么？
所以我现在正在读取一个 csv 文件，当我执行上面的代码时，它会像字符串一样打印出来，出于某种原因，python 烧瓶似乎只让我这样打印出来，尽管尝试你的缩进提示，就像本地主机说的那样“JSON对象必须是str，bytes或bytearray，而不是list”，是因为python flask我不能正确缩进吗？我正在网络浏览器上查看它
或者有没有办法通过将数据作为字典来做到这一点？
