Converting dictionary to JSON

Question

r     is claimed    True    rating   3 5  r   json dumps r  file write str r  rating       I am not able to access my data in the JSON  What am I doing wrong   TypeError  string indices must be integers  not str

No need to convert it in a string by using json.dumps()

r = {'is_claimed': 'True', 'rating': 3.5}
file.write(r['is_claimed'])
file.write(str(r['rating']))

You can get the values directly from the dict object.

json dumps   returns the JSON string representation of the python dict  See the docs  You can t do r  rating   because r is a string  not a dict anymore  Perhaps you meant something like  r     is claimed    True    rating   3 5  json   json dumps r    note i gave it a different name file write str r  rating

json dumps   is used to decode JSON data  json loads take a string as input and returns a dictionary as output  json dumps take a dictionary as input and returns a string as output   import json    initialize different data str data    normal string  int data   1 float data   1 50 list data    str data  int data  float data  nested list    int data  float data  list data  dictionary          int   int data       str   str data       float   float data       list   list data       nested list   nested list      convert them to JSON data and then print it print  String     json dumps str data   print  Integer     json dumps int data   print  Float     json dumps float data   print  List     json dumps list data   print  Nested List     json dumps nested list  indent 4   print  Dictionary     json dumps dictionary  indent 4      the json data will be indented  output  String    quot normal string quot  Integer   1 Float   1 5 List     quot normal string quot   1  1 5  Nested List         1      1 5                 quot normal string quot           1          1 5         Dictionary          quot int quot   1       quot str quot    quot normal string quot        quot float quot   1 5       quot list quot              quot normal string quot           1          1 5             quot nested list quot             1          1 5                         quot normal string quot               1              1 5                     Python Object to JSON Data Conversion                    Python                    JSON      --------------------------------------   ------                      dict                    object                   list  tuple                 array                       str                    string     int  float  int-  amp  float-derived Enums   number                      True                     true                       False                    false                      None                     null

Defining r as a dictionary should do the trick    gt  gt  gt  r  dict     is claimed    True    rating   3 5   gt  gt  gt  print r  rating    3 5  gt  gt  gt  type r   lt class  dict  gt

json dumps   converts a dictionary to str object  not a json dict  object  So you have to load your str into a dict to use it by using json loads   method  See json dumps   as a save method and json loads   as a retrieve method   This is the code sample which might help you understand it more   import json  r     is claimed    True    rating   3 5  r   json dumps r  loaded r   json loads r  loaded r  rating    Output 3 5 type r   Output str type loaded r   Output dict
