How to remove subset dictionaries from list of dictionaries
问题
我有一个字典列表，其中一些是子集：
l = [
{'zero': 'zero', 'one': 'example', 'two': 'second'},
{'zero': 'zero', 'one': 'example', 'two': 'second', 'three': 'blabla'},
{'zero': 'zero'},
{'zero': 'non-zero', 'one': 'example'}, ...
]
我想创建一个新的字典列表，其中不包含字典的子集。
res = [
{'zero': 'zero', 'one': 'example', 'two': 'second', 'three': 'blabla'},
{'zero': 'non-zero', 'one': 'example'}, ...
]
英文:
I have a list of dictionaries, and some of them are subsets:
l = [
{'zero': 'zero', 'one': 'example', 'two': 'second'},
{'zero': 'zero', 'one': 'example', 'two': 'second', 'three': 'blabla'},
{'zero': 'zero'},
{'zero': 'non-zero', 'one': 'example'}, ...
]
And I want to create a new list of dictionaries that do not contain a subset of dictionaries.
res = [
{'zero': 'zero', 'one': 'example', 'two': 'second', 'three': 'blabla'},
{{'zero': 'non-zero', 'one': 'example'}, ...
]

这段代码的目的是创建一个新的列表，该列表仅包含不是其他字典的子集的字典。
res = [
d for d in l
if not any(set(d.items()).issubset(set(other.items()))
for other in l if other != d)
]
print(res)
输出结果为：
[
{'zero': 'zero', 'one': 'example', 'two': 'second', 'three': 'blabla'},
{'zero': 'non-zero', 'one': 'example'}
]
英文:
This work around will create a new list that only contains dictionaries that are not subsets of any other dictionary in the list
res = [
d for d in l
if not any(set(d.items()).issubset(set(other.items()))
for other in l if other != d)
]
print(res)
Output:
[{'zero': 'zero', 'one': 'example', 'two': 'second', 'three': 'blabla'},
{'zero': 'non-zero', 'one': 'example'}]
