Classes are a sort of templates that create objects with related data and functions that can be used to manipulate that data.
define your class using the format: "class User:"
create a user : <user1 = user()> user1 is an instance or an object of the class. Attach data to your object: <user1.first_name = "John"> Data attached to the object is a Field (first_name)
Access data same way its been assigned: <print(user1.first_name)> CLASSES are used to make objects , and each object can have different value for the same variable names, example: <user2.first_name = "Tommy"> This is stored into user2 though it contains the same variable first_name.
Different users can be created and different fields can be created for each user, which can be of any type, example: <user1.age = 20> <user2.hobby = "Axe-Throwing"> <user3.is_sitting = True>
Init methods are to initialise our class. functions inside classes are called methods. init is a constructor that is a method called whenever there is a first instance in the class. it starts with the argument (self) which is a reference to the new object that is being created, additional arguments can be added. example: <class User: def init(self, name, age, hobby, is_sitting):>
Then we store the values to fields in the object, like so <class User: def init(self, name, age, hobby, is_sitting): self.name = name self.age = "34" self.hobby= "Axe-Throwing" is_sitting= True >
GOOD PRACTISE: To add help text, type a docstring than use <help(User)>
SUMMARY : classes group together data , and related functions into a sort of machine to create many objects
