Question

我试图完成与this问题相似的事情。但是我得到了关键错误，因为并非所有列表都是平等创建的。我不确定对我的案例最好的做法是什么。

我的词典列表是动态的，我试图匹配＆＃39; id＆＃39;的键/值。

示例列表是：

    data_keys: [[{
    'pre_conditions': [],
    'id': 436,
    'tc_steps': [{
        'expected': 'Enter_APN: PleaseentertheAPN',

    },

    }],
    'title': "Route from 'apn_match' to 'AskDOB'"
}]]

我想在这个列表中最终只有7个（在这种情况下）dicts

这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)

Answer 1

上述代码中发现了两个问题：

您在"tc_step"使用itemgetter，而密钥为"tc_steps"
您正在使用"tcs_cannot_route"，而某些记录中不存在此密钥

也可能存在其他问题。
