Class.instance Python Code Example

Example 1: 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!

Example 2: making an instance of a class in puython

#!/usr/bin/python  class Employee:    'Common base class for all employees'    empCount = 0     def __init__(self, name, salary):       self.name = name       self.salary = salary       Employee.empCount += 1        def displayCount(self):      print "Total Employee %d" % Employee.empCount     def displayEmployee(self):       print "Name : ", self.name,  ", Salary: ", self.salary  "This would create first object of Employee class" emp1 = Employee("Zara", 2000) "This would create second object of Employee class" emp2 = Employee("Manni", 5000) emp1.displayEmployee() emp2.displayEmployee() print "Total Employee %d" % Employee.empCount

Example 3: 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.  #example # 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
