我正在从该网站 API 中提取信息： https ://financialmodelingprep.com/

具体来说，我需要损益表中的数据：

https://financialmodelingprep.com/developer/docs/#Company-Financial-Statements

我从 API 返回的是一个列表，其中包含 36 个字典，其中包含以下数据：

[ {
  "date" : "2019-09-28",
  "symbol" : "AAPL",
  "fillingDate" : "2019-10-31 00:00:00",
  "acceptedDate" : "2019-10-30 18:12:36",
  "period" : "FY",
  "revenue" : 260174000000,
  "costOfRevenue" : 161782000000,
  "grossProfit" : 98392000000,
  "grossProfitRatio" : 0.378178,
  "researchAndDevelopmentExpenses" : 16217000000,
  "generalAndAdministrativeExpenses" : 18245000000,
  "sellingAndMarketingExpenses" : 0.0,
  "otherExpenses" : 1807000000,
  "operatingExpenses" : 34462000000,
  "costAndExpenses" : 196244000000,
  "interestExpense" : 3576000000,
  "depreciationAndAmortization" : 12547000000,
  "ebitda" : 81860000000,
  "ebitdaratio" : 0.314636,
  "operatingIncome" : 63930000000,
  "operatingIncomeRatio" : 0.24572,
  "totalOtherIncomeExpensesNet" : 422000000,
  "incomeBeforeTax" : 65737000000,
  "incomeBeforeTaxRatio" : 0.252666,
  "incomeTaxExpense" : 10481000000,
  "netIncome" : 55256000000,
  "netIncomeRatio" : 0.212381,
  "eps" : 2.97145,
  "epsdiluted" : 2.97145,
  "weightedAverageShsOut" : 18595652000,
  "weightedAverageShsOutDil" : 18595652000,
  "link" : "https://www.sec.gov/Archives/edgar/data/320193/000032019319000119/0000320193-19-000119-index.html",
  "finalLink" : "https://www.sec.gov/Archives/edgar/data/320193/000032019319000119/a10-k20199282019.htm"
}, ...
]

我在字典中不需要的是键：fillingDate、acceptedDate、link、finalLink

我设法删除了它们，但我的问题是现在我写的那段代码经常吐出那些字典，我不明白为什么......

这是我尝试过的：

import requests
import json

url = "https://financialmodelingprep.com/api/v3/income-statement/AAPL?apikey=b60bb3d1967bb15bfb9daaa4426e77dc"
response = requests.get(url)
data = response.text
dataList = json.loads(data)
entriesToRemove = {
    'fillingDate' : 0,
    'acceptedDate' : 0,
    'link' : 0,
    'finalLink' : 0
}
removedEntries = []
newDict = {}

for index in range(len(dataList)):
    for key in dataList[index]:
        newDict[key] = dataList[index].get(key)                 
        if key in entriesToRemove:                              
            removedEntries = newDict.pop(key)                   
        print(json.dumps(newDict, indent=4))

操作：

对于字典中的每个键，字典都会打印一个新时间。

原因：

for index in range(len(dataList)):
for key in dataList[index]:
    newDict[key] = dataList[index].get(key)                 
    if key in entriesToRemove:                              
        removedEntries = newDict.pop(key)                   
    print(json.dumps(newDict, indent=4))    # notice this line

为每个键打印字典的原因是因为您在循环中为字典的每次迭代都有一个print(json.dumps(newDict, indent=4))语句。key-val

要从 dict 列表中消除突出显示的键，您可以遍历列表并创建另一个 dict 列表，而不需要不必要的键：

s = [ {
  "date" : "2019-09-28",
  "symbol" : "AAPL",
  "fillingDate" : "2019-10-31 00:00:00",
  "acceptedDate" : "2019-10-30 18:12:36",
  "period" : "FY",
  "revenue" : 260174000000,
  "costOfRevenue" : 161782000000,
  "grossProfit" : 98392000000,
  "grossProfitRatio" : 0.378178,
  "researchAndDevelopmentExpenses" : 16217000000,
  "generalAndAdministrativeExpenses" : 18245000000,
  "sellingAndMarketingExpenses" : 0.0,
  "otherExpenses" : 1807000000,
  "operatingExpenses" : 34462000000,
  "costAndExpenses" : 196244000000,
  "interestExpense" : 3576000000,
  "depreciationAndAmortization" : 12547000000,
  "ebitda" : 81860000000,
  "ebitdaratio" : 0.314636,
  "operatingIncome" : 63930000000,
  "operatingIncomeRatio" : 0.24572,
  "totalOtherIncomeExpensesNet" : 422000000,
  "incomeBeforeTax" : 65737000000,
  "incomeBeforeTaxRatio" : 0.252666,
  "incomeTaxExpense" : 10481000000,
  "netIncome" : 55256000000,
  "netIncomeRatio" : 0.212381,
  "eps" : 2.97145,
  "epsdiluted" : 2.97145,
  "weightedAverageShsOut" : 18595652000,
  "weightedAverageShsOutDil" : 18595652000,

res = []
ignored_keys = ['fillingDate', 'acceptedDate', 'link', 'finalLink']
for dd in s:
    for k,v in dd.items():
        if k not in ignored_keys:
            res.append({k: v})      
print(res)

单线：

print({k:v for dd in s for k,v in dd.items() if k not in ignored_keys})
