An attribute is a named value associated with an object. Attribute lookup exposes data and behavior through objects, classes, and built-in types. section 10.6
Create an instance attribute
Assign an argument to self.flavor inside __init__. Calling Scoop('chocolate') creates an instance whose flavor attribute contains 'chocolate'. section 10.6 section 10.8
Use attributes while practicing these object-oriented patterns:
- Store instance state such as a beverage's name and temperature, including a default temperature. section 10.8
- Attach an opened file to a LogFile instance through its file attribute. section 10.8
- Combine attributes with composition by giving a Shelf books and width, then checking capacity. section 10.12
- Use class-level declarations and annotations with dataclasses, while recognizing that type checking remains external. section 10.12
from dataclasses import dataclass
@dataclass
class Scoop():
flavor : str
A minimal dataclass declaration shows an annotated flavor attribute without writing __init__ manually. section 10.12
