### Sets ###

#sets aren't organised, that is why they are similar to dictionaries

my_other_set = {'Mike', 'Treyu', 22}
print(type(my_other_set))

print(len(my_other_set))

#print(my_other_set[0]) this doesn't work with sets. TypeError: 'set' object is not subscriptable

my_other_set.add('Miketreyu')

print(my_other_set) #a set isn't an ordered structure

my_other_set.add('Miketreyu') # a set doesn't admit repeated data

print(my_other_set)

print('Mike' in my_other_set)
print('Miki' in my_other_set)

my_other_set.remove('Mike')
print(my_other_set)

#print(my_other_set) NameError: name 'my_other_set' is not defined
