Write a note on object.

Write a note on self argument used in python class function.

Write a python program to find total and average marks using class.

Explain the working of the following program. class Sample:
def _init_(self, num):
print("Constructor of class Sample ...")
self.num=num
print("The value is :", num)
S=Sample(10)

Write the output of the following program.
class Sample:
num=0
def _init_(self, var):
Sample.num+=1
self. var=var
print("The object value is = ", var)
print("The count of object created Sample.num) =",
S1=Sample(15)
S2=Sample(35)
S3=Sample(45)

Why the following program give an error while displaying the value of n2. Give Reason.

Write a python program that illustrate the use of destructor.

Fill up the blanks in the following program to get the output:
Value of x = 10
Value of y = 20
Sum of x and y= 30
Class sample:
x, __ = 10, 20 -------------------1
s = -------------------------2
print ("value of x =", __ ) ------------3
print ("value of y =", __ ) -------------4
print ("sum of x and y =", __ ) --------5

Read the following program. Answer the following question. Class sample:
x, y= 10, 20
s= sample ()
print (s. x + s. y)
1. What does sample denotes?
2. What does x, y denotes?
3. What does s denotes?

Write a program to define a class and syntax for class instantiation
class Sample:
#class variables
x, y = 10, 20
S = Sample() #class instantiation
print ("value of_x=", S.x)
print ("value of_y=", S.y)
print ("value of x and y =", S.x + S.y)
