      Object and Classes

      Python Tutorial

      This Python tutorial has been written for the beginners to help them understand the basic to advanced concepts of Python Programming Language. After completing this tutorial, you will find yourself at a great level of expertise in Python, from where you can take yourself to the next levels to become a world class Software Engineer.

      Object and Classes

      Python is a highly object-oriented language. In Python, each and every element in a Python program is an object of one or the other class. A number, string, list, dictionary etc. used in a program they are objects of corresponding built-in classes.

      Example

      num=20
      print (type(num))
      num1=55.50
      print (type(num1))
      s="TutorialsPoint"
      print (type(s))
      dct={'a':1,'b':2,'c':3}
      print (type(dct))
      def SayHello():
         print ("Hello World")
         return
      print (type(SayHello))
      When you execute this code, it will produce the following output
      <class 'int'>
      <class 'float'>
      <class 'str'>
      <class 'dict'>
      <class 'function'>
      In Python, the Object class is the base or parent class for all the classes, built-in as well as user defined.
      The class keyword is used to define a new class. The name of the class immediately follows the keyword class followed by a colon as follows
      class ClassName:
         'Optional class documentation string'
         class_suite
      • The class has a documentation string, which can be accessed via ClassName.__doc__.
      • The class_suite consists of all the component statements defining class members, data attributes and functions.

      Example

      class Employee(object):
         'Common base class for all employees'
         pass
      Any class in Python is a subclass of object class, hence object is written in parentheses. However, later versions of Python don't require object to be put in parentheses.
      class Employee:
         'Common base class for all employees'
         pass
      To define an object of this class, use the following syntax
      e1 = Employee()
