why is set data type useful in python code example

Example 1: python data types

# Pyhton data types

# Integer
age = 18

# Float (AKA Floating point number)
current_balance = 51.28

# Boolean
is_tall = False # can be set to either True or False

# String
message = "Have a nice day"

# List
my_list = ["apples", 5, 7.3]

# Dictionary
my_dictionary = {'amount': 75}

# Tuple
coordinates = (40, 74) # can NOT be changed later

# Set
my_set = {5, 6, 3}

Example 2: what is the type of the data python

>>> type(1234)
<class 'int'> 
>>> type(55.50) 
<class 'float'>  
>>> type(6+4j)   
<class 'complex'> 
>>> type("hello") 
<class 'str'>     
>>> type([1,2,3,4]) 
<class 'list'>      
>>> type((1,2,3,4)) 
<class 'tuple'>     
>>> type({1:"one", 2:"two", 3:"three"}
<class 'dict'>
