Classes and Objects

Fill Code in the Blanks

#Practice 1
class __________:
def __init__(_____________):
self.name = name
self.age = age

p1 = Person(“Ram”, 42)

print(__________) #prints name in p1
print(__________) #prints age in p1

#Practice 2
class Person:
def __init__(self, fname, lname):
___________= fname
___________ = lname

def ______________:
print(self.firstname, self.lastname)

x = _____________________
x.printname()

  1. Write a program to define a class called student and store his personal details like and name, age, height and weight. Create two objects out of the class and initialise their values by yourself as developer.

  2. Create a method inside ‘Student’ class created in exercise no.1 and define functions to accept user input and display the data. Create an object and get user input for the data members of the object.

  3. Create a class named ‘Rectangle’ with a method named ‘Area’ which returns the area and length and breadth passed as parameters to its constructor.
  4. Create class ‘Employee’ and define its constructor with three variables name, year of joining, salary and address. Also define methods to accept user input and display output
