Day #31 - Sets in Python

Introduction

Welcome to my 31st blog post. We have learned about list, tuples datatype, today I learned about another similar datatype which is an unordered collection of well-defined objects. It is called a set. Let's dive into more details.

So let's get started......

What is a set?

It is an unordered collection of data items.
They store multiple items in a single variable.
Set items are separated by commas and enclosed within curly brackets {}.
They are unchangeable, meaning you cannot change items of the set once created. Sets do not contain duplicate items.

Example -

#set does not take repeated values 
#Set is a unordered collection of well defined objects. Set does not maintain order

s = {2,4,2,6}
print(s)

{2, 4, 6}

Example -

info = {"Carla", 19, False, 5.9, 19}
print(info)

{False, 19, 5.9, 'Carla'}

In the above example, we see that the items of the set occur in random order and hence they cannot be accessed using index numbers. Sets do not allow duplicate values.

Empty set

Below is the code to create an Empty set

#create empty set
set1 = {}      #the way to make dict and set is same. So here type is dict

print(type(set1))

#to create empty set use below syntax
set2 = set()
print(type(set2))

<class 'dict'>
<class 'set'>

Accessing set Items

Using a For loop - You can access items of set using a for loop.

info = {"Carla", 19, False, 5.9}
for item in info:
    print(item)

Output -

False
Carla
19
5.9

Note: all the operations similar to list can be performed on sets except that repetition of values is not allowed.
