Printing Nested Dictionaries with Indentation

Python's pprint module provides a convenient pprint() function for printing data structures in a readable format. However, it does not indent nested structures by default.

Solution Using JSON Serializer

One approach is to take advantage of the JSON serializer's ability to handle nested data. By dumping the dictionary to JSON and then printing the result using the indent parameter, you can achieve the desired indentation. Here's how:

import json

mydict = {'key1': ['value1', 'value2'], 'key2': {'value1': 4, 'value2': 5}}

print(json.dumps(mydict, sort_keys=True, indent=4))

This will produce output with tabbed indentation:

{
    "key1": [
        "value1",
        "value2"
    ],
    "key2": {
        "value1": 4,
        "value2": 5
    }
}
