如何使用python提取json中指定字段的数据

Answer 1

首先你获取的json数乎链据是字符串a的话，就
import json
d = json.loads(a)
x =d.get("想要岁伏孙的字段")
x就是厅磨你要的数据

Answer 2

使用json包中的json.loads将该字符串转换为Python字典。 代码如下：

import json

json_data = """{
"favourite":{
"bkmrk":{
"id1490843709594066":{
"guid":"904eff52277f403b89f6410fe2758646.11",
"lcate"胡镇:"1"
},
"id1490843712805183":{
"guid":"58457f60eca64025bc43a978f9c98345.16",
"lcate":"2"
},
"id149084371467327":{
"guid":"a0f907f9dc8b40f689b083f3eba7228b.16",
"lcate":"3"
},
"id1490843716295393":{
"guid":"eb75d929455e468bb712e7bc2025d11a.16",
"携羡lcate"裤隐粗:"4"
}
}
}
}"""

data = json.loads(json_data)
for v in data['favourite']['bkmrk'].values():
print("%s;%s" % (v['lcate'], v['guid']))
