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()
