Their is going to be a relatively big jump in difficulty here, but dont be scared!
|
||
|
|
All you need to know to understand classes are variables and functions, as covered in the previous file.
|
||
|
|
|
||
|
|
Key Concepts:
|
||
|
|
**class** is a blueprint for creating objects (specific instances of that class),
|
||
|
|
a class represents a collection of attributes and methods to represent something (e.g a Person)
|
||
|
|
|
||
|
|
**object** is an instance of a class with its own unique data.
|
||
|
|
|
||
|
|
**attributes** are values tied to a object
|
||
|
|
|
||
|
|
**methods** are the exact same as functions, but are tried to a class.
|
||
|
|
|
||
|
|
**Magic/dunder methods** are methods predefined by python that can be used for various things.
|
||
|
|
|
||
|
|
**__init__** is a type of magic method, it is known as a constructor and initializes the objects attributes when its created
|
||
|
