python--- JsonPath從多層嵌套Json中解析所需要的值

dic =   {
        "error_code": 0,
        "stu_info": [
                {
                        "id": 2057,
                        "name": "xiaohei",
                        "sex": "nan",
                        "age": 29,
                        "addr": "beijing",
                        "grade": "tianxie",
                        "phone": "18712321234",
                        "gold": 100
                }
        ]
}
import jsonpath
s = jsonpath.jsonpath(dic,'$..name')   #不管有多少層，寫兩個.都能取到
print(s) #['xiaohei'] 返回的是一個列表
s = jsonpath.jsonpath(dic,'$..hehe')   #當不存在hehe這個key時，返回false
print(s)  #False
