Python 字典来自 API 有 1 个标题我想摆脱

Question

所以这就是我从 API 得到的，但我真的不需要第一个“红利”标题

{
    "dividends": [
        {
            "currency": "USD",
            "date": "2021-05-04",
            "dividend": "0.1100",
            "dividend_prior": "",
            "dividend_type": "Cash",
            "dividend_yield": "0.0878828229027963",
            "ex_dividend_date": "2021-05-18",
            "exchange": "AMEX",
            "frequency": 12,
            "id": "6091befc99cf5000019edaf3",
            "importance": 0,
            "name": "Pioneer Diversified High",
            "notes": "",
            "payable_date": "2021-05-28",
            "record_date": "2021-05-19",
            "ticker": "HNW",
            "updated": 1620164698
        },
        {
            "currency": "USD",
            "date": "2021-05-04",
            "dividend": "0.0475",
            "dividend_prior": "",
            "dividend_type": "Cash",
            "dividend_yield": "0.0449526813880126",
            "ex_dividend_date": "2021-05-18",
            "exchange": "NYSE",
            "frequency": 12,
            "id": "6091bf0999cf5000019edaff",
            "importance": 0,
            "name": "Pioneer Municipal High IT",
            "notes": "",
            "payable_date": "2021-05-28",
            "record_date": "2021-05-19",
            "ticker": "MHI",
            "updated": 1620164711
        },

我让它与 header=False 一起工作，但是当放入 csv 文件时，它不会从中获取正确的新标题

        "currency": "USD",
        "date": "2021-05-04",
        "dividend": "0.1100",
        "dividend_prior": "",
        "dividend_type": "Cash",
        "dividend_yield": "0.0878828229027963",
        "ex_dividend_date": "2021-05-18",
        "exchange": "AMEX",
        "frequency": 12,
        "id": "6091befc99cf5000019edaf3",
        "importance": 0,
        "name": "Pioneer Diversified High",
        "notes": "",
        "payable_date": "2021-05-28",
        "record_date": "2021-05-19",
        "ticker": "HNW",
        "updated": 1620164698

output 看起来像这样：

不应该将标题作为列名，然后根据列对齐所有内容吗？

这是我到目前为止使用的代码：

response_dumped = json.dumps(response)
response_parsed = json.loads(response_dumped)
df = pd.DataFrame(response_parsed)
df.to_csv("main_data.csv", index=False, header=False)

我将如何实现这一目标？

Answer 1

你很接近，select 数据按主要dividends ：

df= pd.DataFrame(esponse_parsed['dividends'])

Answer 2

import pandas as pd
json = {
    "dividends": [
        {
            "currency": "USD",
            "date": "2021-05-04",
            "dividend": "0.1100",
            "dividend_prior": "",
            "dividend_type": "Cash",
            "dividend_yield": "0.0878828229027963",
            "ex_dividend_date": "2021-05-18",
            "exchange": "AMEX",
            "frequency": 12,
            "id": "6091befc99cf5000019edaf3",
            "importance": 0,
            "name": "Pioneer Diversified High",
            "notes": "",
            "payable_date": "2021-05-28",
            "record_date": "2021-05-19",
            "ticker": "HNW",
            "updated": 1620164698
        },
        {
            "currency": "USD",
            "date": "2021-05-04",
            "dividend": "0.0475",
            "dividend_prior": "",
            "dividend_type": "Cash",
            "dividend_yield": "0.0449526813880126",
            "ex_dividend_date": "2021-05-18",
            "exchange": "NYSE",
            "frequency": 12,
            "id": "6091bf0999cf5000019edaff",
            "importance": 0,
            "name": "Pioneer Municipal High IT",
            "notes": "",
            "payable_date": "2021-05-28",
            "record_date": "2021-05-19",
            "ticker": "MHI",
            "updated": 1620164711
        }]}
no_header = json["dividends"]
df = pd.DataFrame(no_header)
df.to_csv("main_data.csv", index=False, header=False)
