如何从json文件中获取嵌套键值
如何从json文件中获取嵌套键值
提问于 2018-07-03 04:32:01
我有以下结构：
{
"$schema": "http:",
"title": "al",
"description": "An enitity ",
"id": "a.json#",
"type": "object",
"required": [
"symbol",
"symbolText",
"gene",
"taxonId",
"primaryId"
],
"additionalProperties": false,
"properties": {
"primaryId": {
"$ref": "..",
"description": "The"
},
"symbol": {
"type": "string",
"description": "The symbol of the entity."
},
"symbolText": {
"type": "string",
"description": "the "
},
"taxonId": {
"$ref": "../g",
"description": "The "
},
"synonyms": {
"type": "array",
"items": {
"type": "string"
},
"uniqueItems": true
},
"secondaryIds": {
"type": "array",
"items": {
"$ref": "."
},
"uniqueItems": true
},
"gene": {
"$ref": "../globalId.json#/properties/globalId",
"description": "The "
},
"crossReferences": {
"description": "Collection",
"type": "array",
"items": {
"$ref": "../crossReference.json#"
},
"uniqueItems": true
}
}
}它保存在名为"my_keywordfile“的文件中。我想要像这样的东西：
$schema.http,
type.object,
...,
**properties.primaryId.$ref,
properties.primaryId.description**下面是我的代码：
json_load = json.load(my_keywordfile)
for key, value in json_load.items():
# print((key,value))
if type(value) == type({}) or type(value) == type([]):
for x in value:
for i in range(0, len(value) > i):
print(key+'.'+value)但是它给了我这个错误：
TypeError: must be str, not list有人知道怎么修吗？它工作得很好，直到下面这行：
for key, value in json_load.items():
print((key,value))本节将在第一级打印出关键字及其值。但是看起来其余的代码有问题！

您需要此行打印x而不是value，您可以删除for i in range(0, len(value) > i):
for x in value:
print(key+'.'+x)Stack Overflow用户

这仍然归功于@Sunitha，因为我刚刚修改了代码以删除最后的值，以及在数据是列表的情况下的索引号。
json_load = json.load(my_keywordfile)
def get_dotted_form(parent,values):
lines = []
if isinstance(values,dict):
for key in values.keys():
# print(keys)
lines+=get_dotted_form(parent+"."+key, values[key])
elif isinstance(values,list):
for i,k in enumerate (values):
# print(keys)
lines+=get_dotted_form(parent+"."+k, values[i])
else:
lines.append(parent)
return [line.lstrip('.') for line in lines]
for x in get_dotted_form("",json_load):
print(x)
