Python 3.x 尝试按字典列表分组时出错python 3.5

我正试图完成类似问题的事情。但是我得到了一个关键错误，因为并不是所有的列表都是平等创建的。。我不确定对我来说最好的行动方案是什么

我的dict列表是动态的，我正在尝试匹配'id'的键/值

一个例子是：

    data_keys: [[{
    'pre_conditions': [],
    'id': 436,
    'tc_steps': [{
        'expected': 'Enter_APN: PleaseentertheAPN',
        'content': 'APN: 8552929487,
        HollyBrowser: ,
        '
    },
    {
        'expected': 'Enter_Test_Date: Pleaseenterthedate',
        'content': 'press*'
    },
    {
        'expected': 'Enter_ANI: ',
        'content': ''
    }],
    'title': "Route from 'Start' to 'GetCallerDetail'"
}],
[{
    'pre_conditions': [],
    'id': 565,

在这个列表中，我希望最后只有7条（在本例中）的dict

以下是我执行此特定任务的代码：

from itertools import groupby
from operator import itemgetter
groups = groupby(data_keys, itemgetter('id', 'title', 'pre_conditions', 'tc_steps', 'tcs_cannot_route'))

edge_data = [{'id': groupinfo[0], 'title': groupinfo[1], 'pre_conditions': groupinfo[2], 'tc_steps': groupinfo[3], 'tcs_cannot_route': groupinfo[4]} for groupinfo, items in groups]

print(edge_data)

---

上述代码中发现了两个问题：

您在

itemgetter

中使用

“tc\u步骤”

，而键是

“tc\u步骤”

您正在使用

“tcs\u cannot\u route”

，而某些记录中不存在此密钥

---

可能还有其他问题。

那么错误是什么，需要的输出是什么？@vincentmajor由于字典中的键不匹配，这是一个键错误。我正试图找到一个解决方案，如果groupby不是答案的话，如何做到这一点。是的，我修复了tc_步骤——我理解这个问题是因为我在所有字典中没有相同的键。我正在想办法解决这个问题？groupby可能不是解决方案……在这种情况下，我建议您发布一个新问题，显示您的数据以及处理数据的预期输出。在这里，你关注的是“如何”而不是“你想要实现什么”，这似乎会导致一条死胡同。
