Dr. Kaufman’s sailboat model & the needs associated with it (Pg2)
The Hull (the butt of the boat): Represents our security & stability needs- things like safety, connection, & self-esteem. If the hull hs “holes” (like trauma, fear, or instability), we can’t really move forward because all our energy goes into surviving or patching it up. These R the foundations that keep the boat steady
The Sail: Stands 4 our growth & exploration needs-curiosity, purpose, love,

API (Application Programming Interface): collection of predefined classes, interfaces, methods (libraries). Java is a simple (easy to learn), object-oriented (uses objects and classes), distributed (supports network-based applications), and interpreted (runs via JVM from bytecode) language. It is robust (strong in error handling and memory management), secure (protects against threats with built-in
...Inheritance in Python
Inheritance allows a class to use and extend the properties and methods of another class.
It promotes code reusability and reduces duplication.
Think of it as “child learns from parent.” 👨👦💻
Program with no Inheritance:
