我正在尝试将其转换为json，格式如下：

{
    "2023-06-30": {
        "Ordinary Shares Number": "7432000000.0",
        ...
    },
    "2022-06-30": {
        "Ordinary Shares Number": "7464000000.0",
        ...
    },
    "2021-06-30": {
        "Ordinary Shares Number": "7519000000.0",
        ...
    },
    "2020-06-30": {
        "Ordinary Shares Number": "7571000000.0",
        ...
    }
}

然而，我试图转换它已经从坏到更坏的范围，所以我真的不知道我在做什么。
我的尝试要么给了我一个非常不受欢迎的JSON格式，要么给了我一个关于时间戳的类型错误：
举例来说：

out = json.dumps({c: dict(zip(balance.index, balance[c])) for c in balance.columns}, indent=4)
print(out)

结果：

Traceback (most recent call last):
  File "/usr/lib/python3.8/runpy.py", line 194, in _run_module_as_main
    return _run_code(code, main_globals, None,
  File "/usr/lib/python3.8/runpy.py", line 87, in _run_code
    exec(code, run_globals)
  File "/home/jesse_b/tools/stonk-db/stonkdb/__main__.py", line 39, in <module>
    main()
  File "/home/jesse_b/tools/stonk-db/stonkdb/__main__.py", line 32, in main
    out = json.dumps({c: dict(zip(balance.index, balance[c])) for c in balance.columns}, indent=4)
  File "/usr/lib/python3.8/json/__init__.py", line 234, in dumps
    return cls(
  File "/usr/lib/python3.8/json/encoder.py", line 201, in encode
    chunks = list(chunks)
  File "/usr/lib/python3.8/json/encoder.py", line 431, in _iterencode
    yield from _iterencode_dict(o, _current_indent_level)
  File "/usr/lib/python3.8/json/encoder.py", line 376, in _iterencode_dict
    raise TypeError(f'keys must be str, int, float, bool or None, '

你可以使用dict-comprehension：

import json

# convert the columns to string before (if needed)
# df.columns = df.columns.astype(str)

out = json.dumps({c: dict(zip(df.index, df[c])) for c in df.columns}, indent=4)
print(out)

我们可以通过将第一列设置为DataFrame的索引，然后使用df.to_json(orient='columns')将其转换为JSON来实现相同的JSON结构。在'columns'方向上，JSON的形状是DataFrame中的每一列都成为一个键，对应的值存储在该键下的数组中。

import pandas as pd
import json

df.set_index(df.columns[0], inplace=True)
result = df.to_json(orient='columns')

parsed = json.loads(result)
print(json.dumps(parsed, indent=4))
