__str__
__str__ is a Python special method that returns an object's informal, human-readable string representation.
Python How-To
__str__ is a Python special method that returns an informal, user-oriented string representation of an object.
- How it is used
- Makes printed instances and f-string interpolation display meaningful, user-oriented information.
- How deep it goes
- Works through an instance-method implementation, its str return value, invocation paths, and its distinction from __repr__.
- Examples
- Shows a Task with title, description, and urgency, plus a Direction enumeration displayed as a lowercase direction.
- What you can do after
- Build it from scratch: define __str__ for a class or enumeration to produce readable instance output.

A Python special method that returns an object's user-oriented string representation.
- How it is used
- Explains how objects can provide readable user-facing representations alongside developer-oriented representations.
- How deep it goes
- Defines the audience distinction and shows a Bowl example, but defers deeper object-model mechanics.
- Examples
- Uses Bowl and Scoop objects, numeric conversion with str(5), and joining converted ranges.
- What you can do after
- Apply it via Python string conversion and object representation choices for readable output.

The Quick Python Book, Fourth Edition
__str__ is Python's special method for producing an informal string representation of an object.
- How it is used
- Uses __str__ to make custom objects readable during printing, debugging, and conversion to user-facing strings.
- How deep it goes
- Explains automatic invocation and demonstrates formatting and recursive delegation, without covering lower-level implementation details.
- Examples
- Demonstrates RGB Color formatting, printed Circle descriptions, and recursive HTML document rendering.
- What you can do after
- Apply it via print() and str() to produce informative representations of custom class instances.
