how to define class in python code example

Example 1: 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!

Example 2: class python

class MyClass(object):

    	print(f'Lucky Lemur is {self.description}')

lucky_lemur = LuckyLemur('Pro')
lucky_lemur.reveal_description()

Example 4: python class

class Person:
  def __init__(self, name, age):
    self.name = name
    self.age = age
  def myfunc(self):
    print("Hello my name is " + self.name +".")

p1 = Person("Victor", 24)
p1.myfunc()

Example 5: python class

class Animal(object): # Doesn't need params but put it there anyways.
    def __init__(self, species, price):
        self.species = species # Sets species name
        self.price = price # Sets price of it
    
    def overview(self): # A function that uses the params of the __init__ function
        print(f"This species is called a {self.species} and the price for it is {self.price}")

class Fish(Animal): # Inherits from Animal
    pass # Don't need to add anything because it's inherited everything from Animal
 
salmon = Fish("Salmon", "$20") # Make a object from class Fish
salmon.overview() # Run a function with it
dog = Animal("Golden retriever", "$400") # Make a object from class Animal
dog.overview() # Run a function with it

Example 6: class and object in python

#NOTES
class PartyAnimal:
  	def Party():
      #blahblah

an=PartyAnimal()

an.Party()# this is same as 'PartyAnimal.Party(an)'
