python - 如何从带有非引号键的字符串中生成有效的 JSON？

Question

我有以下python问题：

'{acorn: 15,acorn_type: 15,area_name: "London",beds_max: 1,beds_min: 1,branch_id: "21062",branch_name: "Realm Estates",brand_name: "Realm Estates",chain_free: false,company_id: "10832",country_code: "gb",county_area_name: "London",currency_code: "GBP",display_address: "Lancaster Mews, Wandsworth SW18",furnished_state: "unfurnished",group_id: "",has_epc: true,has_floorplan: false,incode: "1BA",is_retirement_home: false,is_shared_ownership: false,listing_condition: "pre-owned",listing_id: 45296714,listing_status: "to_rent",listings_category: "residential",location: "London",member_type: "agent",num_baths: 1,num_beds: 1,num_images: 5,num_recepts: 1,outcode: "SW18",post_town_name: "London",postal_area: "SW",price: 1300,price_actual: 1300,price_max: 1500,price_min: 1250,price_qualifier: "",property_highlight: "",property_type: "flat",region_name: "London",section: "to-rent",size_sq_feet: "",tenure: "",zindex: "686544"}'

我想要json.load()这个字符串，但显然所有的键都是错误的。它应该是'acorn: 15,...等等。我怎么能把 a 之前的所有单词都替换:成一个字符串？谢谢

根据@daniel-roseman 评论，最好使用 yaml 将字符串加载到 dict 中：

import yaml,json
string='{acorn: 15,acorn_type: 15,area_name: "London",beds_max: 1,beds_min: 1,branch_id: "21062",branch_name: "Realm Estates",brand_name: "Realm Estates",chain_free: false,company_id: "10832",country_code: "gb",county_area_name: "London",currency_code: "GBP",display_address: "Lancaster Mews, Wandsworth SW18",furnished_state: "unfurnished",group_id: "",has_epc: true,has_floorplan: false,incode: "1BA",is_retirement_home: false,is_shared_ownership: false,listing_condition: "pre-owned",listing_id: 45296714,listing_status: "to_rent",listings_category: "residential",location: "London",member_type: "agent",num_baths: 1,num_beds: 1,num_images: 5,num_recepts: 1,outcode: "SW18",post_town_name: "London",postal_area: "SW",price: 1300,price_actual: 1300,price_max: 1500,price_min: 1250,price_qualifier: "",property_highlight: "",property_type: "flat",region_name: "London",section: "to-rent",size_sq_feet: "",tenure: "",zindex: "686544"}'
dict_version = yaml.safe_load(string)
print dict_version

#if you need json version
json_version = json.dumps(dict_version)
print json_version

这给了你：
