根據列表中元素的數量過濾嵌套字典

Question

如何根據 ID 必須包含三個或更多時間戳的條件過濾以下字典？

dict={10009: {196962305: [Timestamp('2019-12-27 03:06:50')]},
 10051: {2854032: [Timestamp('2019-12-27 19:16:11')],
  48600461: [Timestamp('2019-12-29 01:56:19')]},
 10061: {62464559: [Timestamp('2019-12-31 02:58:48'), Timestamp('2019-12-30 21:35:15'), Timestamp('2019-12-28 09:27:55'), [Timestamp('2019-12-28 12:05:32')]}}

所需的 output：

new_dict={10061: {62464559: [Timestamp('2019-12-31 02:58:48'), Timestamp('2019-12-30 21:35:15'), Timestamp('2019-12-28 09:27:55'), [Timestamp('2019-12-28 12:05:32')]}}

Answer 1

嘗試這個：

如果內部字典只有一個鍵，它將起作用

res = {k: v for k, v in d.items() if len(list(v.values())[0]) > 2}
print(res)

Output：

{10061: {62464559: [Timestamp('2019-12-31 02:58:48'), Timestamp('2019-12-30 21:35:15'), Timestamp('2019-12-28 09:27:55'), [Timestamp('2019-12-28 12:05:32')]]}}
