15. LOOPS IN
PYTHON
www.edureka.co
Why Should
We Use One?
How Many
Types Of
Loops?
Iterating Over
A Sequence?

16. Why Should
We Use
Loops?
www.edureka.co
Suppose you want to print the numbers
from 0-10
0,1,2,3,4,5,6,7,8,9,10
You want to print the sum of all even
numbers until 100.
You want to print the name of all employees
in a sequence until you come across lets
say ‘Ravi Mehta’
OR
OR

17. www.edureka.co
Why FOR Loop?
When we are iterating over a
sequence.
You know the number of
times the statements will get
executed.

18. www.edureka.co
Why WHILE Loop?
When we are executing a set
of statements , if the
condition holds true.
The execution stops as soon
as the condition is false.

22. FUNCTIONS
IN PYTHON

HOW TO
DECLARE A
FUNCTION?

03 HOW ARE WE
GOING TO PASS
VALUES IN A
FUNCTION?
WHY USE
FUNCTIONS?

23. Why Use
Functions?
www.edureka.co
I have to write the
logic for Factorial
again and again
Instead You can define a function to
calculate factorial. And you can call
that function every time you need to
calculate factorial.

26. CLASSES &
OBJECTS
www.edureka.co
WHAT IS A
CLASS?
WHY ARE WE
USING THEM?
WHAT IS AN
OBJECT?

27. Why Use
Classes?
www.edureka.co
You can define a class with
various methods/functions
You can access and
modify the data
stored in methods
using the object of the
class.
A class is basically a definition of an
object

Abstraction Polymorphism
Encapsulation Inheritance

31. www.edureka.co
Creating a parent class
Inheriting properties to a
derived class or child class
Base Class
Derived Class
You can access methods and
properties from either classes by
creating the objects.
