classes python 3 code example
Example 1: 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.width
Example 2: class python
class MyClass(object):
def __init__(self, x):
self.x = x
Example 3: 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 4: class python 3
A class is a block of code that holds various functions. Because they
are located inside a class they are named methods but mean the samne
thing. In addition variables that are stored inside a class are named
attributes. The point of a class is to call the class later allowing you
to access as many functions or (methods) as you would like with the same
class name. These methods are grouped together under one class name due
to them working in association with eachother in some way.
