Class in Python

Introductions of Class:

Class:

• Class is used to hold data members and member function i.e. variables and functions.
• It can be easily accessed anywhere and used to reduce the reusability of the code.
• The class name is a user-defined word.

For example,

• Let’s take student,
• Student properties are all called variables and student performance or student-related calculations(i.e. student result based on total and it may be pass or fail) is called as a function.

Where,

The student is a class.

Student properties (variables) : Roll_num,name,age,ect.

Student behaviours(function)  : total,average,result,fees details ect.

Note:

• If one or more variables declared within the class, called data members.
• If one or more functions declared within the class, called member function.

Syntax:

1. import module_name#optional

   class class_name:

       def function_name(list_of_patameters):

           #Statements

       function_name(list_of_patameters)#Function calling

Example program:

1. class calculator:

       def add(x,y):

           return x+y

       def sub(x,y):

           return x-y

       def mul(x,y):

           return x*y

       def div(x,y):

           return x/y

       a,b=input("Enter two values: ").split()

       print("Add value:",add(int(a),int(b)))

       print("Sub value:",sub(int(a),int(b)))

       print("Mul value:",mul(int(a),int(b)))

       print("Div value:",div(int(a),int(b)))
