类型错误字符串索引必须是整数

Question

迭代字典时出现类型错误。 类型错误字符串索引必须是整数

data = {"GetEventHeadlines_Response_1":{"EventHeadlines":{"Headline":[{"CountryCode":"US","EventType":"EarningsCallsAndPresentations","Duration":{"EndDateTime":"2019-12-30T12:00:00","EndQualifier":"None","IsEstimate":false,"StartDateTime":"2019-12-30T12:00:00","StartQualifier":"DateTime"},"EventId":12969284,"LastUpdate":"2020-01-02T19:06:09.267","LiveDialIn":{"Duration":{"EndDateTime":"2019-12-30T12:00:00","EndQualifier":"None","IsEstimate":false,"StartDateTime":"2019-12-30T12:00:00","StartQualifier":"DateTime"},"Password":"6378226","PhoneNumber":"+1-845-675-0437","Status":"Available"},"LiveWebcast":{"Type":"ThirdParty","Duration":{"EndDateTime":"2019-12-30T14:00:00","EndQualifier":"DateTime","IsEstimate":false,"StartDateTime":"2019-12-30T12:00:00","StartQualifier":"DateTime"},"WebcastId":"840B9947-C69D-40E5-AF4F-4F35B1FF069C","Provider":"WindowsMedia","Url":null},"Name":"Q3 2019 Nio Inc Earnings Call","ReplayDialIn":{"Duration":{"EndDateTime":"2020-01-07T12:59:00","EndQualifier":"DateTime","IsEstimate":false,"StartDateTime":"2019-12-30T15:00:00","StartQualifier":"DateTime"},"Password":"6378226","PhoneNumber":"+1-646-254-3697","Status":"Available"},"ReplayWebcast":{"Type":"ThirdParty","Duration":{"EndDateTime":"2020-01-30T12:00:00","EndQualifier":"DateOnly","IsEstimate":false,"StartDateTime":"2019-12-30T14:00:00","StartQualifier":"DateTime"},"WebcastId":"0816103B-4559-4816-BE2A-BC1B5612486B","Provider":"WindowsMedia","Url":null},"Transcript":{"Status":"Final","TranscriptId":"8874A5B3-06BC-4863-9890-9F6775E1A219","DeliveryType":"Live","Locale":"en-US"},"Organization":{"Name":"Nio Inc","Symbols":{"Symbol":[{"Type":"RIC","Value":"NIO.N"}]}},"RsvpRequired":false}]},"PaginationResult":{"PageNumber":1,"RecordsOnPage":1,"RecordsPerPage":100,"TotalRecords":1}}}

用False转换你的false ，它会起作用。 我使用了另一种方法，将其作为原始字符串，然后将其转换为 JSON。 这样，JSON 的实际布尔值将转换为 Python 方式。

import json
data = r'''{"GetEventHeadlines_Response_1":{"EventHeadlines":{"Headline":[{"CountryCode":"US","EventType":"EarningsCallsAndPresentations","Duration":{"EndDateTime":"2019-12-30T12:00:00","EndQualifier":"None","IsEstimate":false,"StartDateTime":"2019-12-30T12:00:00","StartQualifier":"DateTime"},"EventId":12969284,"LastUpdate":"2020-01-02T19:06:09.267","LiveDialIn":{"Duration":{"EndDateTime":"2019-12-30T12:00:00","EndQualifier":"None","IsEstimate":false,"StartDateTime":"2019-12-30T12:00:00","StartQualifier":"DateTime"},"Password":"6378226","PhoneNumber":"+1-845-675-0437","Status":"Available"},"LiveWebcast":{"Type":"ThirdParty","Duration":{"EndDateTime":"2019-12-30T14:00:00","EndQualifier":"DateTime","IsEstimate":false,"StartDateTime":"2019-12-30T12:00:00","StartQualifier":"DateTime"},"WebcastId":"840B9947-C69D-40E5-AF4F-4F35B1FF069C","Provider":"WindowsMedia","Url":null},"Name":"Q3 2019 Nio Inc Earnings Call","ReplayDialIn":{"Duration":{"EndDateTime":"2020-01-07T12:59:00","EndQualifier":"DateTime","IsEstimate":false,"StartDateTime":"2019-12-30T15:00:00","StartQualifier":"DateTime"},"Password":"6378226","PhoneNumber":"+1-646-254-3697","Status":"Available"},"ReplayWebcast":{"Type":"ThirdParty","Duration":{"EndDateTime":"2020-01-30T12:00:00","EndQualifier":"DateOnly","IsEstimate":false,"StartDateTime":"2019-12-30T14:00:00","StartQualifier":"DateTime"},"WebcastId":"0816103B-4559-4816-BE2A-BC1B5612486B","Provider":"WindowsMedia","Url":null},"Transcript":{"Status":"Final","TranscriptId":"8874A5B3-06BC-4863-9890-9F6775E1A219","DeliveryType":"Live","Locale":"en-US"},"Organization":{"Name":"Nio Inc","Symbols":{"Symbol":[{"Type":"RIC","Value":"NIO.N"}]}},"RsvpRequired":false}]},"PaginationResult":{"PageNumber":1,"RecordsOnPage":1,"RecordsPerPage":100,"TotalRecords":1}}}'''

Answer 2

我试过在这里复制代码并进行测试，但没有出现错误。 我确实编辑了几个值，例如 false 到 False 但仅此而已。 我得到的结果如下：

{'Q3 2019 Nio Inc 收益电话'：'8874A5B3-06BC-4863-9890-9F6775E1A219'}

2019年第三季度蔚来公司财报电话8874A5B3-06BC-4863-9890-9F6775E1A219

这是代码，以防我错误地复制它。
