Iterate through a nested Dictionary and Sub Dictionary in Python

Question

JSON:

data = {"result":[{"name":"Teddy","list":{"0":"24","1":"43","2":"56"}},
           {"name":"Barney","list":{"0":"24","1":"43","2":"56"}]}

Code:

i = 0
j = 0
for p in data['result']:
    print('Name: ' + p['name'])
    for v in p['list']:
        i += 1
        print("{0} : {1}".format(i,v[j]))
        j += 1

I am trying to access each value and print them out, but unfortunately, without any success, any help is appreciated.

I have seen: Loop through all nested dictionary values?

`i` and `j` don't seem to be related to the data in any way at all. — Daniel Roseman, Dec 21 '16 at 18:35
Eh, see my JSON, I am (not seen here), but I load this into a dictionary, and then I am trying to iterate over it. — haxxir411, Dec 21 '16 at 18:37
What does "without any success" mean? Can you post the results? Also, can you specify what the expected output is? — brianpck, Dec 21 '16 at 18:38
It means, that I am doing something wrong, for some reason I am unable to access the keys in the list dictionary "0", "1", and "2". — haxxir411, Dec 21 '16 at 18:40
Note that at the end of your `data`, you need to add another `}` like this `..."2":"56"}}]}` — ettanany, Dec 21 '16 at 18:48
Because you did not close curly braces for the second element! — ettanany, Dec 21 '16 at 18:51

From your attempt, seems that what you want to do is the following:

data = {"result":[
    {"name":"Teddy","list":{"0":"24","1":"43","2":"56"}},
    {"name":"Barney","list":{"0":"24","1":"43","2":"56"}}]}

for p in data['result']:
    print('Name: ' + p['name'])
    for k, v in p['list'].items():
        print("{0} : {1}".format(k,v))

Note that data is not a JSON object but a Python dictionary.

Output:

Name: Teddy
1 : 43
0 : 24
2 : 56
Name: Barney
1 : 43
0 : 24
2 : 56

AttributeError: 'dict' object has no attribute 'iteritems' – haxxir411 Dec 21 '16 at 18:45
@haxxir411 Which version of Python are you using? 2 or 3? – ettanany Dec 21 '16 at 18:47
Where to check? – haxxir411 Dec 21 '16 at 18:47
Python 3.5.2 (v3.5.2:4def2a2901a5 – haxxir411 Dec 21 '16 at 18:48
So you should use `items()` instead of `iteritems()` – ettanany Dec 21 '16 at 18:48
Thx a lot :-) :) :) – haxxir411 Dec 21 '16 at 18:50
