'Def' or Define

Self

Inside the functions in a class, self is a variable for the instance/object being accessed.

Inheritance

Composition

The concept that a class can be composed of other classes as parts, much like how a car has wheels

Attribute

Is-a

A phrase to say that something inherits from another, as in a ”salmon” is-a ”fish.”

Has-a

A phrase to say that something is composed of other things or has a trait, as in ”a salmon has-a mouth.”
