方法一：
from collections import defaultdict
a_dict = {'aa': {1, 2, 3, 5}, 'bb': {2, 3, 4, 5}, 'cc': {3, 4, 5}}
a_set = set()
result = defaultdict(set)
for k, v in a_dict.items():
a_set = a_set | v
for i in a_set:
dict_key = list()
for key in a_dict:
if i in a_dict[key]:
dict_key.append(key)
result['_'.join(sorted(dict_key))].add(i)
print(result)
方法二：
from functools import reduce
def intersect(x,y):
return x | y
def search_relation(datas):
dic_values = reduce(intersect, datas.values())
data = {}
for i in dic_values:
dict_key = list()
for k,v in datas.items():
if i in v:
dict_key.append(k)
if '_'.join(dict_key) in data:
data['_'.join(dict_key)].add(i)
else:
dict_value = set()
dict_value.add(i)
data['_'.join(dict_key)] = dict_value
print(data)
if __name__ == '__main__':
all_data = {'aa': {1, 2, 3, 5}, 'bb': {2, 3, 4, 5}, 'cc': {3, 4, 5}}
search_relation(all_data)
