我有一個帶有嵌套字典的串列作為串列元素。有 12 個這樣的字典,每個字典有 107 個鍵值對,作為下面第一個字典的快照:
big_list = [{0: 0.9065934065934067,

我想構建一個回圈,通過它我可以以這種方式提取值:
first_dict[key1][value]
second_dict[key1][value]
third_dict[key1][value]
...
twelfth_dict[key1][value]
...
first_dict[key107][value]
...
twelfth_dict[key107][value]
對每個字典中的每個鍵依此類推,然后找到字典中每個鍵的平均值,即鍵 1、鍵 2 到鍵 106 的平均值。我知道零可能會使事情復雜化,但它們是必需的任務。請讓我知道這是否可行,如果需要,我很樂意進一步詳細說明。謝謝。

如果字典鍵是升序的,您可以先遍歷鍵:
big_list = [{
0: 0.9065934065934067,
1: 0.0,
2: 0.14285714285714288,
3: 0.03663003663003663,
4: 0.0,
5: 0.0
}, {
0: 0.9065934065934067,
1: 0.0,
2: 0.14285714285714288,
3: 0.03663003663003663,

}]
longestDict = max(len(d.keys()) for d in big_list) # determine longest dictionary, in case they are not equal sized.
for key in range(0, longestDict):
print(f"Key: {key}")
for dct in big_list:
print(f"\t{dct.get(key, None)}")
出去:
