python functions in class code example

Example 1: how to declare a class in python

class ClassName(object): #"(object)" isn't mandatory unless this class inherit from another
  	def __init__(self, var1=0, var2):
    
    	#the name of the construct must be "__init__" or it won't work
    	#the arguments "self" is mandatory but you can add more if you want 
    	self.age = var1
    	self.name = var2
    
    	#the construct will be execute when you declare an instance of this class
    
  	def otherFunction(self):
    	
        #the other one work like any basic fonction but in every methods,
    	#the first argument (here "self") return to the class in which you are

Example 2: class methods in python

from datetime import date

# random Person
class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    @classmethod
    def fromBirthYear(cls, name, birthYear):
        return cls(name, date.today().year - birthYear)

    def display(self):
        print(self.name + "'s age is: " + str(self.age))

person = Person('Adam', 19)
person.display()

person1 = Person.fromBirthYear('John',  1985)
person1.display()

# If questions ask SK3#3160 he can help you i think
def ok(index):
    print(index) > Hi!
ok("Hi!")
class Lib:
    def ok(self,Token):
        print(Token) > Hello World!
