How to get a dictionary from a json file in Python?

Question

I got this code for implementing my needing:

import json

json_data = []
with open("trendingtopics.json") as json_file:
    json_data = json.load(json_file)

for category in json_data:
    print category
    for trendingtopic in category:
        print trendingtopic

And this is my json file:

{
    "General": ["EPN","Peña Nieto", "México","PresidenciaMX"],
    "Acciones politicas": ["Reforma Fiscal", "Reforma Energética"]
}

However I'm getting this printed:

Acciones politicas
A
c
c
i
o
n
e
s

p
o
l
i
t
i
c
a
s
General
G
e
n
e
r
a
l

I want to get a dictionary being Strings the keys and got a list as value. Then iterate over it. How can I accomplish it?

Answer 1

json_data is a dictionary. In your first loop, you're iterating over a list of the dictionary's keys:

for category in json_data:

category will contain key strings - General and Acciones politicas.

You need to replace this loop, which iterates over keys' letters:

for trendingtopic in category:

with the below, so that it iterates over the dictionary elements:

for trendingtopic in json_data[category]:
