我有两个词:
A={'a':{"total":5,"all":[100,101]},'b':{"total":10,"all":[200,201]}}
B={'a':{"q1":"a","q2":"aa"},'b':{"q1":"b"},'c':{"q1":"c","q2":"ccc"}}
我根据键(a,b,c)组合了dicts中的所有值,如下所示:
import collections
super_dict = collections.defaultdict(set)
for k, v in chain(A.items(), B.items()):
#related_datasets = v.get("all")
#total_downloads = v.get("total")
#query_1 = v.get("q1")
#query_2 = v.get("q2")
super_dict.setdefault(k, []).append(v)
这导致了(super_dict):
defaultdict(set,
{'a': [{'all': [100, 101], 'total': 5}, {'q1': 'a', 'q2': 'aa'}],
'b': [{'all': [200, 201], 'total': 10}, {'q1': 'b'}],
'c': [{'q1': 'c', 'q2': 'ccc'}]})
但是,我想生成一个super_dict,如下所示:
{'a': {'all': [100, 101], 'q1': 'a', 'q2': 'aa', 'total': 5},
'b': {'all': [200, 201], 'q1': 'b', 'total': 10},
'c': {'q1': 'c', 'q2': 'ccc'}}
任何帮助将不胜感激。
好的,我找到了解决方案:
import collections
super_dict = {}
for k, v in chain(A.items(), B.items()):
related_datasets = v.get("all")
total_downloads = v.get("total")
query_1 = v.get("q1")
query_2 = v.get("q2")
vkeys = v.keys()
if k in super_dict.keys():
super_dict[k].update(v)
else:
super_dict[k]= v

你很亲密:
A={'a':{"total":5,"all":[100,101]},'b':{"total":10,"all":[200,201]}}
B={'a':{"q1":"a","q2":"aa"},'b':{"q1":"b"},'c':{"q1":"c","q2":"ccc"}}
from itertools import chain
import collections
super_dict = collections.defaultdict(dict)
for k, v in chain(A.items(), B.items()):
super_dict[k].update(v)
super_dict
答案 1 :(得分:1)
A={'a':{"total":5,"all":[100,101]},'b':{"total":10,"all":[200,201]}}
B={'a':{"q1":"a","q2":"aa"},'b':{"q1":"b"},'c':{"q1":"c","q2":"ccc"}}
d = {}
for key in set(A.keys() + B.keys()):
try:
d.setdefault(key,{}).update(A[key])
except KeyError:
pass
try:
d.setdefault(key,{}).update(B[key])
except KeyError:
pass
print d

{'a': {'q1': 'a', 'q2': 'aa', 'all': [100, 101], 'total': 5}, 'c': {'q1': 'c', 'q2': 'ccc'}, 'b': {'q1': 'b', 'all': [200, 201], 'total': 10}}
答案 2 :(得分:0)
A={'a':{"total":5,"all":[100,101]},'b':{"total":10,"all":[200,201]}}
B={'a':{"q1":"a","q2":"aa"},'b':{"q1":"b"},'c':{"q1":"c","q2":"ccc"}}
C = {}
C['a'] = {**A['a'], **B['a']}
C['b'] = {**A['b'], **B['b']}
C['c'] = {**B['c']}
print(C)
打印结果(C)使用最新版本的Python - C是你的 super_dict。
