How to Pretty Print Nested Dictionaries in Python without losing Indentation?

Pretty Printing Nested Dictionaries

Pretty printing nested dictionaries in Python can be a challenge, especially when dealing with significant depth. While the pprint() module provides some functionality for formatting nested structures, it may not always produce the desired indentations.

Solution: Using the JSON Serializer

One effective solution is to leverage the JSON serializer's ability to format nested dictionaries. Here's an example:

<code class="python">import json

data = {'a': 2, 'b': {'x': 3, 'y': {'t1': 4, 't2': 5}}}

# Serialize and pretty print the dictionary
json_string = json.dumps(data, sort_keys=True, indent=4)
print(json_string)</code>

This code will generate a neatly formatted JSON representation of the dictionary, with 4 spaces of indentation for each level:

{
    "a": 2,
    "b": {
        "x": 3,
        "y": {
            "t1": 4,
            "t2": 5
        }
    }
}
