我在这里扩展我的原始问题:How to append/merge list of dictionaries?
我正在尝试将一些数据合并到一个包含列表的字典列表中。如果“object”和“semver”键匹配,则会根据它们进行合并。如果相同的值匹配,也会添加到给定的“部分”。鉴于以下数据:
data = [
{
"semver":"1.0.0",
"sections":[
{
"name":"Add",
"messages":[
"add: comment here"
]
}
],
"object":"files.sh"
},
{
"semver":"1.0.0",
"sections":[
{
"name":"Add",
"messages":[
"add: Second comment here"
]
}
],
"object":"files.sh"
},
{
"semver":"1.0.0",
"sections":[
{
"name":"Fix",
"messages":[
"Comment here"
]
}
],
"object":"files.sh"
},
{
"semver":"2.0.0",
"sections":[
{
"name":"Fix",
"messages":[
"2.0.0 Fix Comment here"
]
}
],
"object":"files.sh"
},
{
"semver":"2.0.0",
"sections":[
{
"name":"Add",
"messages":[
"2.0.0 Add Comment here"
]
}
],
"object":"files.sh"
},
{
"semver":"2.0.0",
"sections":[
{
"name":"Add",
"messages":[
"2.0.0 comment for the NewFile"
]
}
],
"object":"NewFile.sh"
},
]
我希望最终实现这一目标
data = [
{
"semver":"1.0.0",
"sections":[
{
"name":"Add",
"messages":[
"add: comment here",
"add: Second comment here"
]
},
{
"name":"Fix",
"messages":[
"Fix: comment here"
]
}
],
"object":"files.sh"
},
{
"semver":"2.0.0",
"sections":[
{
"name":"Add",
"messages":[
"2.0.0 Add comment here",
]
},
{
"name":"Fix",
"messages":[
"2.0.0 Fix Comment here"
]
}
],
"object":"files.sh"
},
{
"semver":"2.0.0",
"sections":[
{
"name":"Add",
"messages":[
"2.0.0 comment for the NewFile"
]
}
],
"object":"NewFile.sh"
},
]
代码块
objects = {} # mapping for object: object_data with sections
sections = defaultdict(list) # mapping for object: all sections
for d in data:
print(d["semver"])
for k, v in list(d.items()):
if v == d["semver"]:
try:
section = d.pop("sections")
sections[d["object"]].extend(section)
objects[d["object"]] = d # populate with object data without sections
except Exception as e:
print(e)
pass
output = []
for object_name, object_data in objects.items():
object_data["sections"] = sections[object_name]
output.append(object_data)
到目前为止,我正在循环遍历dict
中的每个k,v对,但无法在两个版本之间进行匹配并附加到循环中的特定dict
应进行两项更改:
objects
和sections
中的键更改为基于元组表示的object
和semver
的组合李>试试这个:
