How to Recursively Print All Values from a Nested Dictionary in Python?

Recursive Looping through Nested Dictionary Values

Problem Statement

Given a nested dictionary, the task is to traverse through all its key-value pairs, printing values that are not nested dictionaries. For nested dictionaries, the traversal should continue recursively to print their key-value pairs.

Solution

Utilizing recursion, a function can be defined to perform this task:

def myprint(d):
    for k, v in d.items():
        if isinstance(v, dict):
            myprint(v)
        else:
            print("{0} : {1}".format(k, v))

This function accepts a dictionary as an argument and iterates through its key-value pairs. If a value is not a nested dictionary, it prints the key-value pair. If the value is a dictionary, it recursively calls the myprint function with this new dictionary.

Example

Consider the following dictionary:

d = {
    "xml": {
        "config": {
            "portstatus": {"status": "good"},
            "target": "1"
        },
        "port": "11"
    }
}

Calling the myprint function would output:

xml : {config: {portstatus: {status: good}, target: 1}, port: 11}
config : {portstatus: {status: good}, target: 1}
portstatus : {status: good}
target : 1
port : 11

This solution provides a recursive mechanism to loop through all nested dictionary values and print them as desired.
