Set Data Types

Sets are unordered collections of unique objects, there are two types of set :

1. Sets - They are mutable and new elements can be added once sets are defined

python basket = {‘apple’, ‘orange’, ‘apple’, ‘pear’, ‘orange’, ‘banana’} print(basket) # duplicates will be removed > {‘orange’, ‘banana’, ‘pear’, ‘apple’} a = set(‘abracadabra’) print(a) # unique letters in a > {‘a’, ‘r’, ‘b’, ‘c’, ‘d’} a.add(‘z’) print(a) > {‘a’, ‘c’, ‘r’, ‘b’, ‘z’, ‘d’}

1. Frozen Sets - They are immutable and new elements cannot added after its defined. python b = frozenset(‘asdfagsa’) print(b) > frozenset({‘f’, ‘g’, ‘d’, ‘a’, ‘s’}) cities = frozenset([“Frankfurt”, “Basel”,“Freiburg”]) print(cities) > frozenset({‘Frankfurt’, ‘Basel’, ‘Freiburg’})
