        driver['URL'],
        driver['SUMARY'],
    ] for driver in updates_data["DownloadData"]
]

我不怀疑从“下载数据”中的哪里可以获得这部分

]用于updates_data[“DownloadData”]中的驱动程序

我不断收到以下错误:

回溯(最后一次调用):文件 “C:/用户/EDMTC7J4/台式机/联想驱动程序刮刀/rryh1.py”,第38行, 在里面 ]对于updates_data[“DownloadData”]中的驱动程序,KeyError:'DownloadData'

我根据这里的帖子做了这件事 I am trying to use python and selenium to create a driver scraper, I need to grab particular data from the web page and put it in csv row and column

我只是需要帮助来理解“下载数据”放在哪里,我很难弄清楚。

它给出KeyError是因为 DownloadData 不存在于 updates_data 。有一个名为的不同密钥 DownloadItems 我假设这是你需要的。

print(updates_data['body'].keys())

>>> dict_keys(['AllCategories', 'AllOperatingSystems', 'AllPriorities', 'DownloadItems', 'ProductId', 'DCGFixIDNamingGuideImageUrl', 'RestrictCountryList'])

您需要进一步浏览词典,以访问您要查找的特定字段,即。 updates_data['body']['DownloadItems']['Files'] 换句话说,一个嵌套的循环要遍历每个 Files 每一个 下载项目 。然后,您可以根据需要组织行项目。

rows = []
for driver in updates_data['body']['DownloadItems']:
    for f in driver['Files']:
        rows.append([
            f['Name'],
            f['Date'],
            f['Version'],
            f['Priority'],
            f['TypeString'],
            f['URL'],
            driver['Summary'],
        ])
