• Flexible API

from exprint import Format, Formatter, dispatch_obj, exprint

class Example:
    __slots__ = "foo", "bar"

    def __init__(self, foo: str, bar: int):
        self.foo = foo
        self.bar = bar


def format_example(obj: Example, f: Formatter) -> Format:
    return f.format_class("Example").field("foo", obj.foo).field("bar", obj.bar)

# Assiocate the format function to its type
dispatch_obj(Example, format_example)

exprint(Example("Hello", 10))
# Output:
# Example { foo: 'Hello', bar: 10 }

Example

import json
from exprint import exprint

# https://github.com/topojson/us-atlas?tab=readme-ov-file#counties-10m.json
with open("./counties-10m.json") as file:
    data = json.load(file)

exprint(data, max_elements=10)

In your terminal, you will have a colored output.
