how to make a class in python
class Person:
def __init__(self, _name, _age):
self.name = _name
self.age = _age
def sayHi(self):
print('Hello, my name is ' + self.name + ' and I am ' + self.age + ' years old!')
p1 = Person('Bob', 25)
p1.sayHi() # Prints: Hello, my name is Bob and I am 25 years old!declare class python
# To create a simple class:
class Shape:
def __init__():
print("A new shape has been created!")
pass
def get_area(self):
pass
# To create a class that uses inheritance and polymorphism
# from another class:
class Rectangle(Shape):
def __init__(self, height, width): # The constructor
super.__init__()
self.height = height
self.width = width
def get_area(self):
return self.height * self.widthpython class

# Classes require an __init__ if you want to assign attributes. (self) defines what describes the attribs.python classes
class Student:

p1 = Student(1, "Jay", 19)
p2 = Student(2, "Jean", 22)
p3 = Student(3, "Shanna", 32)
p4 = Student(4, "Kayla", 23)

"Why should I use classes in python?"
Classes are essential in OOP.
A good reason to use classes is to make your code structured and organised.
Furthermore it is easy to import functions when they are part of a class since you can just import the class.
Classes provide methods that are useful such as the __repr__ method which allows you to represent an object by a string.
Classes allow for access control (encapsulation) by using the underscore character.Copyright © 2021 Codeinu
