Classes In Python

This is a description of Python class:

>> class Data:

>>    def __init__(self,fname,age):

>>         this.fname = fname

>>         this.age = age

>>    lname = "no defined last name"

>>    def setFName(self,fname):

>>        this.fname = fname

>>    def setAge(self, age):

>>        this.age = age

>>    def getFName(self):

>>        return this.fname

>>    def getAge(self):

>>        return this.age

To instantiate an object of class Data, use:

>> lady = Data("Lady",24);

>> print lady.getFName()

>> print lady.getAge()

>> print lady.lname

Always use bracket when instantiate an object of a class, although there's no argument in the constructor. For data, no use of "self". For method, always "self" as the first argument in function declaration to allow it accessed from outside.
