LESSON 5

Question 1

ENCAPSULATION is also known as

Answer 1

DATA HIDING

Question 2

Python is always Private (True or false)

Answer 2

False - PUBLIC

Question 3

loophole of python is not secured (true or false)

Answer 3

True

Question 4

Python uses “ _ _ “ in order to be Object Oriented Paradigm (True or false)

Answer 4

True

Question 5

● ____ is one of the
important building blocks of object oriented programming which
enables the wrapping of all data
(attributes and methods) into a
single component(class)
● This prevents the accidental
modification of data by imposing
some restrictions on accessing
variables or methods directly.

Answer 5

Encapsulation

Question 6

is the process of hiding
the data of an entity from others to
prevent the accidental modification
of data by other entities

Answer 6

Data hiding

Question 7

Based on the visibility of the object’s attribute in a
class, they can be classified in two, which are __

Answer 7

private and public

Question 8

If a data member or member function is
accessible from any part of the program, it is
considered as

Answer 8

public

Question 9

If its visibility is restricted to the defined class, then
it is considered as

Answer 9

private

Question 10

Access modifiers are ___ elements of
object-oriented programming as they restrain the
access to the attributes and methods in a class.

Answer 10

inevitable

Question 11

Python does have specific access modifiers
like C, Java, and other languages. (True or False)

Answer 11

False - DOES NOT HAVE

Question 12

Python being an object-oriented programming
language makes use of underscores to perform
the function of access modifiers that are done in
other languages (True or False)

Answer 12

True

Question 13

In Python, all attributes are private by default. (True or False)

Answer 13

FALSE - PUBLIC

Question 14

Any data or member function that prefixes with
double underscore is private to that class (TRUE OR FALSE)

Answer 14

(True)

Question 15

● ___ is the process of hiding internal
implementation of a process from its end user,
showing only essential features of data to the
external world
● This is done to reduce complexity and increase
efficiency.
● In the context of programming, isolating the
signature of a method from its definition is known

Answer 15

Abstraction

Question 15

Abstraction in Python is achieved through the use of
abstract classes and methods in programs (TRUE OR FALSE)

Answer 15

TRUE

Question 15

Benefits of Encapsulation

Answer 15

● The attributes of a class can be made read-only or
write-only.
● A class can have total control over what is stored in its
attributes.
● The users of a class do not know how the class stores its
data. A class can change the data type of a field and
users of the class do not need to change any of their
code

Question 16

● It generally focuses on ideas rather than the
functionality. This means the user is only familiar to
“what it does”, not on “how it does it”.

Answer 16

ABSTRACTION

Question 17

is a class which contains one or more
abstract methods.

Answer 17

abstract class

Question 18

A class becomes an abstract class if and only if it contains
at least one abstract method (TRUE OR FALSE)

Answer 18

TRUE

Question 19

A method is said to be an abstract method if it is declared
and defined. (TRUE OR FALSE)

Answer 19

FALSE - DECLARED BUT NOT DEFINED

Question 20

Python does not support any abstract
class, but we can achieve it by importing a class
named

Answer 20

ABC(Abstract Base Class)

Question 21

Abstract methods, on the other hand, are created by
using the

Answer 21

pass parameter

Question 22

An Abstract class in Python can contain the both
normal and abstract method, unlike in others where
an abstract class should only contain abstract
methods. (TRUE OR FALSE)

Answer 22

TRUE

Question 23

Creating an object of an abstract class in Python will
not result in any errors, unlike in others that will result
in ___, since abstract classes cannot be
instantiated

Answer 23

TypeError
