Sets

• unlike lists and tuples, sets are unordered (do not record element position)

music_genres_1 = {'ballad', 'bop', 'rock', 'bop', 'RnB', 'disco'}
print(music_genres_1)
# -> duplicate items will not be present in Sets

RnB

1/ .set()

list1 = ['kevinph4n', 'is', 'handsome', 'handsome', 2008]
list1_set = set(list1)
print(list1_set)

2008

2/ .add()

A = {"thriller", "ballad", "rnb"}
A.add("kevin")
print(A)

ballad

A = {"thriller", "ballad", "rnb"}
A.add("kevin")
"kevin" in A
