How to format floats in a nested dictionary?

[pinikop]

I have a nested dict and some of the (nested) values are floating numbers. how can I integrate a custom formatter that can specify the number of significant digits?

perhaps it would be a good idea to add an option of float formating?

def custom_formatter(x):
    # Check if x is a float and format it to 2 significant digits
    if isinstance(x, float):
        return f'{x:.2f}'
    # Recursively apply the formatter to nested dictionaries and lists
    elif isinstance(x, dict):
        return {k: custom_formatter(v) for k, v in x.items()}
    elif isinstance(x, list):
        return [custom_formatter(v) for v in x]
    else:
        return x

input:

my_dict = {
    "value1": 1.234567,
    "value2": {
        "value3": 2.345678,
        "value4": [3.456789, 4.567890],
    },
    "value5": [
        5.678901,
        {"value6": 6.789012}
    ]
}

desire output: ic(my_dict)

ic| my_dict: {'value1': 1.23,
              'value2': {'value3': 2.34, 'value4': [3.45, 4.56]},
              'value5': [5.67, {'value6': 6.78}]}
