class methods 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: python define class

class uneclasse():
  def __init__(self):
    pass
  def something(self):
    pass
xx = uneclasse()
xx.something()

Example 3: python classes

class Box(object): #(object) ending not required
  def __init__(self, color, width, height): # Constructor: These parameters will be used upon class calling(Except self)
    self.color = color # self refers to global variables that can only be used throughout the class
    self.width = width
    self.height = height
    self.area = width * height
  def writeAboutBox(self): # self is almost always required for a function in a class, unless you don't want to use any of the global class variables
    print(f"I'm a box with the area of {self.area}, and a color of: {self.color}!")

greenSquare = Box("green", 10, 10) #Creates new square
greenSquare.writeAboutBox() # Calls writeAboutBox function of greenSquare object

Example 4: class python

class MyClass(object):
  def __init__(self, x):
    self.x = x

Example 5: classes in python

class Foo:
  def __init__(self):
    self.definition = Foo!
  def hi():
    # Some other code here :)
    
# Classes require an __init__ if you want to assign attributes. (self) defines what describes the attribs.

Example 6: call instance class python

# define class
class example:
# define __call__ function
   def __call__(self):
       print("It worked!")
# create instance
g = example()
# when attempting to call instance of class it will call the __class method
g()
# prints It worked!
