如何将 pandas df 转换为这种 json 结构？

Question

假设我有这样一个 pandas df：

| name   | color of clothing | age |occupation|
| John   | yellow            | 34  | janitor  |
| Carl   | red               | 27  | doctor   |
| Claire | green             | 33  | teacher  |
| Lisa   | blue              | 21  | Student  |
|........|...................| ....|..........|

我想将其转换为 json 格式，如下所示：

[
{ "name": "John,
"color of clothing": "yellow",
"age":"34",
"occupation": "janitor"
},
{ "name": "Carl",
"color of clothing": "red",
"age":"27",
"occupation": "doctor"
},
{ "name": "Claire",
"color of clothing": "green",
"age":"33",
"occupation": "teacher"
},
{ "name": "Lisa",
"color of clothing": "blue",
"age":"21",
"occupation": "student"
}
]

我该怎么做？我最近的匹配是使用 df.to_json(orient="index") 但我得到的是这样的结构：

{"0":{ "name": "John,
"color of clothing": "yellow",
"age":"34",
"occupation": "janitor"
}
},
"1":{ "name": "Carl",
"color of clothing": "red",
"age":"27",
"occupation": "doctor"
}}
...

非常感谢您的帮助！

Answer 1

使用df.to_dict('records')

>>> df
   a  b  c  d
0  1  1  1  1
1  2  2  2  2
>>> df.to_dict('records')
[{'a': 1, 'b': 1, 'c': 1, 'd': 1}, {'a': 2, 'b': 2, 'c': 2, 'd': 2}]
