How to Pretty Print Nested Dictionaries with Indentation?

Pretty Printing Nested Dictionaries

Problem

You want to prettify a deeply nested Python dictionary with an indentation for each level, achieving an output like:

key1
    value1
    value2
    key2
       value1
       value2

However, pprint.PrettyPrinter() alone does not provide the desired output.

Solution

The JSON serializer can effectively handle nested dictionaries. Here's how you can leverage it:

<code class="python">import json

mydict = {'a': 2, 'b': {'x': 3, 'y': {'t1': 4, 't2': 5}}}
print(json.dumps(mydict, sort_keys=True, indent=4))</code>

Output:

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