documented

Templated docstrings for Python classes.

Features

• Describe your business logic in docstrings of your classes and exceptions;
• When printing an object or an exception, the library will substitute the placeholders in the docstring text with runtime values,
• And you (or your user) will see a human-readable text.

Installation

pip install documented

Example

from dataclasses import dataclass
from documented import DocumentedError


@dataclass
class InsufficientWizardryLevel(DocumentedError):
    """
    🧙 Your level of wizardry is insufficient ☹

        Spell: {self.spell}
        Minimum level required: {self.required_level}
        Actual level: {self.actual_level} {self.comment}
