2. (a) List four characteristics of Object Oriented Programming. 2

(b) class Test: 2
rollno=1
marks=75
def_init_(self,r,m): #function 1
self.rollno=r
self.marks=m
def assign(self,r,m): #function 2
rollno = n
marks = m
def check(self): #function 3
print self.rollno,self.marks
print rollno,marks

(i) In the above class definition, both the functions – function 1 as well as
function 2 have similar definition. How are they different in execution ?

(ii) Write statements to execute function 1 and function 2.
