jsonpath provides a convenient way to find a key in a multidimensional dictionary, you must know oh ~

Usage is as follows:

Import jsonpath 
# This is a complex json string 
D = {
     " code " : 200 is ,
     " Message " : " ! success " ,
     " Result " : [{
         " SID " : " 29,668,676 " ,
         " text " : " If employees than boss money " ,

}

# If we need to find the value of the video, the conventional method is 
Print (D [Result] [0] [video])
 # use jsonpath 
Result = jsonpath.jsonpath (D, ' $ .. video ' )
 # $ outermost representatives, whether this key location can be found where. If a plurality of corresponding Key, then returns a list

= D2 {
     " STU " : {
         " Sex " : ' M ' ,
         " House " : {
             " Bejing " : { " Ring " : 5, " tricyclic " : 4 },
             " Shanghai " : { " Pudong " : . 4 } 
        } 
    } 
} 
Print (D2 [ ' STU ' ] [ 'house'][' Shanghai ' ] [ ' Pudong ' ]) 
result2 = jsonpath.jsonpath (D2, ' $ .. Pudong ' )     # Whether this can be found in key locations where 
result3 = jsonpath.jsonpath (D2, ' $ .stu.house ' ) # $ on behalf of the outermost layer, you can always point down 
# If you can not find the corresponding key, the result is False
