Python 3.x 如何从字典列表中删除或消除所有包含一个列表值的字典？

我有一个字典列表，我希望从列表中的每个字典中删除或删除所有包含一个列表值的字典。这是一个字典示例，它有一个列表值

（{'10.48.18.47'：['07:46:06']}）

。这是字典列表的一个示例：

[{'10.0.0.155': ['19:48:46', '20:15:46', '19:49:37', '20:15:08', '19:48:46', '19:47:30', '19:49:13', '20:15:50', '19:45:34', '19:45:33', '19:49:13', '19:49:16', '19:49:36', '19:50:02', '19:54:25', '20:15:06', '19:45:25', '20:15:49', '19:55:10', '19:47:33'], '192.168.1.240': ['16:23:40', '16:23:39', '16:23:20'], '192.168.0.242': ['20:14:07', '20:14:09']}, {}, {'10.48.18.47': ['07:46:06']}, {}, {'0.0.0.0': ['21:19:02', '21:45:21', '21:22:04', '21:18:53', '21:38:47', '21:22:52', '21:38:49', '21:22:05', '21:18:55', '21:22:03', '21:18:45', '21:19:01', '21:22:53', '21:18:25', '21:38:51', '21:22:09', '21:18:15'], '192.168.1.193': ['20:09:24', '20:33:57', '20:09:13', '20:09:39', '20:09:29', '20:03:06', '20:09:33', '20:33:58', '20:09:19', '20:09:38', '20:09:37', '20:18:28', '20:09:17', '20:09:22', '20:33:59', '20:29:53', '20:07:47', '20:09:36', '20:18:29', '20:03:04', '20:34:00'], '172.16.12.31': ['18:57:32'], '192.168.1.120': ['20:43:06', '20:43:05', '20:43:04'], '192.168.1.186': ['20:18:36']}]

这是我的代码：

My_list = [mhist, mhist1,mhist2,mhist3,mhist4]

print (My_list)

while {} in My_list:

    My_list.remove({})

for dect in My_list:

    count = sum(len(v) for v in dect.values())

    print (count)

您可以尝试：

>>> data = [{'10.0.0.155': ['19:48:46', '20:15:46', '19:49:37', '20:15:08', '19:48:46', '19:47:30', '19:49:13', '20:15:50', '19:45:34', '19:45:33', '19:49:13', '19:49:16', '19:49:36', '19:50:02', '19:54:25', '20:15:06', '19:45:25', '20:15:49', '19:55:10', '19:47:33'], '192.168.1.240': ['16:23:40', '16:23:39', '16:23:20'], '192.168.0.242': ['20:14:07', '20:14:09']}, {}, {'10.48.18.47': ['07:46:06']}, {}, {'0.0.0.0': ['21:19:02', '21:45:21', '21:22:04', '21:18:53', '21:38:47', '21:22:52', '21:38:49', '21:22:05', '21:18:55', '21:22:03', '21:18:45', '21:19:01', '21:22:53', '21:18:25', '21:38:51', '21:22:09', '21:18:15'], '192.168.1.193': ['20:09:24', '20:33:57', '20:09:13', '20:09:39', '20:09:29', '20:03:06', '20:09:33', '20:33:58', '20:09:19', '20:09:38', '20:09:37', '20:18:28', '20:09:17', '20:09:22', '20:33:59', '20:29:53', '20:07:47', '20:09:36', '20:18:29', '20:03:04', '20:34:00'], '172.16.12.31': ['18:57:32'], '192.168.1.120': ['20:43:06', '20:43:05', '20:43:04'], '192.168.1.186': ['20:18:36']}]

你可以试试这个-

for dct in d:
    for key in dct.copy():
        if len(dct[key]) <= 1:
           dct.pop(key,None)

d=[{'10.0.0.155'：['19:48:46'，'20:15:46'，'19:49:37'，'20:15:08'，'19:48:46'，'19:47:30'，'19:49:13'，'20:15:50'，'19:45:34'，'19:45:33'，'19:49:13'，'19:49:36'，'19:50:02'，'19:54:25'，'20:15:06'，'19:45:25'，'20:15:49'，'19:25'，'19:47:33'，'168.1.24:24'，'20:23''192:242''['20:14:07', '20:14:09']}, {}, {'10.48.18.47': ['07:46:06']}, {}, {'0.0.0.0': ['21:19:02', '21:45:21', '21:22:04', '21:18:53', '21:38:47', '21:22:52', '21:38:49', '21:22:05', '21:18:55', '21:22:03', '21:18:45', '21:19:01', '21:22:53', '21:18:25', '21:38:51', '21:22:09', '21:18:15'], '192.168.1.193': ['20:09:24', '20:33:57', '20:09:13', '20:09:39', '20:09:29', '20:03:06', '20:09:33', '20:33:58', '20:09:19', '20:09:38', '20:09:37', '20:18:28', '20:09:17', '20:09:22', '20:33:59', '20:29:53', '20:07:47', '20:09:36', '20:18:29', '20:03:04', '20:34:00'], '172.16.12.31': ['18:57:32'], '192.168.1.120': ['20:43:06', '20:43:05', '20:43:04'], '192.168.1.186': ['20:18:36']}]
对于d中的dct：
对于dct.copy（）中的键：
if len（dct[key]）非常感谢您的关注。我可以看到在字典列表的末尾有两个包含一个列表值的字典没有被删除或删除。您能帮我删除它们吗。这些字典是“'172.16.12.31'：['18:57:32']”和“'192.168.1.186'：['20:18:36']”
