使用 Python 生成包含列表作为 JSON 值的字典

Question

我有来自 API 的 JSON 响应，其中列出了许可证到期时间。一个公司可能拥有多个许可证。 JSON 有很多我不需要的数据。我所需要的只是公司名称和许可证到期日期列表。 我的想法是提取所有公司名称并将它们用作字典键，然后值将是包含许可证到期日期的列表。我可以提取公司名称并创建一个以公司名称作为键的字典，但我不知道如何收集许可证日期并将其与特定公司关联起来。

以下是 API JSON 响应的示例。它被截断为仅包含来自同一“测试”公司的两条记录（我相信这足以证明结构），但完整的输出将有多个拥有多个许可证的公司。

因此“company_name”包含公司名称值，“expiration_time”包含许可证到期日期。

    },
    "total_licenses": 247
  }
}

我现在的代码看起来像这样

def ExtractLicenseDetails():
    LicenceLibrary = dict()
    TempOrgList = []
    for licence in lic["data"]:
        TempOrgList.append(licence["attributes"]["organization"]["data"]["attributes"]["name"])
    LicenceLibrary = dict.fromkeys(TempOrgList, list()) # no we create dictionary keys from non unique list of organisation, getting rid of duplicates in the process
    for licence in lic["data"]:
         LicenceLibrary[licence["attributes"]["organization"]["data"]["attributes"]["name"]].append(licence["attributes"]["expiration_time"])
    print(LicenceLibrary)

不用说，它不起作用，但我的意思是错误的到期日期被添加到列表中。

你的代码看起来有点不直观，正如评论已经说过的那样，如果你提供一个 mre 以及代码的正确和实际输出，那就太好了，无论如何，这就是我会做的（+mre）：

lic = {

expiration_dates = {}

for licence in lic["data"]:

    expiration_time = licence["attributes"]["expiration_time"]
    if name in expiration_dates.keys():
        expiration_dates[name].append(expiration_time)
    else:
        expiration_dates[name] = [expiration_time]


print(expiration_dates)
