我有一份清单:List 如何合并具有相同键的dict列表?,list,dictionary,merge,key,List,Dictionary,Merge,Key,我有一份清单: list=[{'Query':'documents'},{'entity':'a'},{'value':'b'},{'entity':'c'},{'value':'d'},{'records':21}] 我要下列订单: d={'Query':['documents'],'entity':['a','c'],'value':['b','d'],'records':[21]} 尝试以下代码: list=[{'Query': 'documents'}, {'entity': 'a'}
list=[{'Query':'documents'},{'entity':'a'},{'value':'b'},{'entity':'c'},{'value':'d'},{'records':21}]
我要下列订单:
d={'Query':['documents'],'entity':['a','c'],'value':['b','d'],'records':[21]}
尝试以下代码:
list=[{'Query': 'documents'}, {'entity': 'a'}, {'value': 'b'}, {'entity': 'c'}, {'value': 'd'}, {'records':21}]
d={}
for i in list :
for j,k in i.items():
l = []
if j in d:
l = d[j]
l.append(k)
d[j] = l
else:
l.append(str(k))
d[j]=l
print(d)
输出:
{'records': ['21'], 'value': ['b', 'd'], 'entity': ['a', 'c'], 'Query': ['documents']}
