Dictionary Recursive indenting

I have the following code that tries to cover most cases of a dictionary walk, and output it as indented text (indent based on the items’ nesting in the dictionary. There are two problems:

1. I think the check at the start, which caters for "raw_list", is a bit of a hack, but I cannot think of a better way
2. I cannot get the level variable to properly reflect its position

Thanks. I think the rest of the recursion is correct…

a = {
    "raw_list" : [1,2,3],
    "a" : 1,
    "b" : 2,
    "mydict": {
        "c":3,
        "d":4
    },
    "mydict2": {
        "c":5,
        "d":6
    },
    "list1": [
        {
            "e1":7, 
            "e2":8
        },
        {
            "e3":9, 
            "e4":10
        }
    ],
    "list2": [
        {
            "f1":11, 
            "f2":12
        }
    ]
}

def process_data(data,level):

    if not isinstance(data,list) and not isinstance(data,dict) :
        print("\t"*level + str(data))
        return

    for element, val in data.items():
        if isinstance(val, dict):
            print("\t"*level + "DICT:" + element)
            level+=1
            process_data(val,level)
        elif isinstance(val, list):
            print("\t"*level + "LIST:" + element)
            level += 1
            for i, item in enumerate(val):
                process_data(item,level)
        else:
            print("\t"*level+element + ":" + str(val))

    level-=1

process_data(a,1)

Got this:

LIST:test
    1
    2
    3
    a:1
    b:2
    DICT:mydict
        c:3
        d:4
        DICT:mydict2
            c:5
            d:6
            LIST:list1
                e1:7
                e2:8
                e3:9
                e4:10
                LIST:list2
                    f1:11
                    f2:12

But want this:

LIST:test
    1
    2
    3
a:1
b:2
DICT:mydict
    c:3
    d:4
DICT:mydict2
    c:5
    d:6
LIST:list1
    e1:7
    e2:8
    e3:9
    e4:10
LIST:list2
    f1:11
    f2:12

>Solution :

You are incrementing the level for each element in a loop. Instead, try removing level += 1 and pass incremented level into the recursive call: process_data(item, level + 1).
