父列表內共有 27 個列表。 問題是每個列表中的鍵都是相同的，我想將所有鍵分組在同一個父列表中的同一個列表下。 我該怎么做呢？

所以代替上面的，我會有類似的東西：

[[{'what-is-contributing-to-the-quarter-on-same-quarter-a-year-ago-decrease?': 'None'},
  {'what-is-contributing-to-the-quarter-on-same-quarter-a-year-ago-decrease?': 'None'},
  {'what-is-contributing-to-the-quarter-on-same-quarter-a-year-ago-decrease?': 'None'},
  {'what-is-contributing-to-the-quarter-on-same-quarter-a-year-ago-decrease?': 'None'},
  {'what-is-contributing-to-the-quarter-on-same-quarter-a-year-ago-decrease?': 'None'},
  {'what-is-contributing-to-the-quarter-on-same-quarter-a-year-ago-decrease?': 'None'},
  {'what-is-contributing-to-the-quarter-on-same-quarter-a-year-ago-decrease?': 'None'}],
 [{'main-points-': 'None'},
  {'main-points-': 'None'},
  {'main-points-': 'None'},
  {'main-points-': 'None'},
  {'main-points-': 'None'},
  {'main-points-': 'None'},
  {'main-points-': 'None'}]]

*** 更新 ***

最初，完成了以下操作：

ids_ = 'what-is-contributing-to-the-quarter-on-same-quarter-a-year-ago-decrease?'
unwind_list = np.concatenate(list_of_list_dict).tolist()
from itertools import groupby

## Just to test with one key. 
def key_func(k):
    return k[ids_]

for key, value in groupby(unwind_list, key_func):
    print(key)
    print(list(value))

上面的問題是它只對具有多個鍵值的字典進行分組，就像大多數解決方案一樣。 例如：

dict_list = {
[{'key':'Value', 'key2':'Value2', 'Key3':'Value3'},
{'key':'Value', 'key2':'Value2', 'Key3':'Value3'},
{'key':'Value', 'key2':'Value2', 'Key3':'Value3'},
{'key':'Value', 'key2':'Value2', 'Key3':'Value3'},]
}

上面按鍵對字典進行排序，而不是我想要的結果。

Answer 1

首先迭代所有子列表和字典並像這樣創建字典會更簡單

{
   key1: [{key1: val1}, {key1: val2}, ...],
   key2: [{key2: val1}, {key2: val2}, ...],
   key3: [{key3: val1}, {key3: val2}, ...],
   ... etc. ...
}

后來只得到沒有鍵的值

[
 [{key1: val1}, {key1: val2}, ...],
 [{key2: val1}, {key2: val2}, ...],
 [{key3: val1}, {key3: val2}, ...],
 ... etc. ...
]
