You can create a set from a list, string, tuple, or dictionary, discarding any duplicative values.

試した。

astring = set( 'letters' )
print(astring)

alist = set( [ 3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5])
print(alist)

atuple = set( (3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5))
print(atuple)

adict = set(  { 'item1': 'double edged sword', 'item2': 'Korejanai Robo'} )
print(adict)
結果
Success	time: 0 memory: 23304 signal:0
set(['s', 'r', 'e', 'l', 't'])
set([1, 2, 3, 4, 5, 6, 9])
set([1, 2, 3, 4, 5, 6, 9])
set(['item2', 'item1'])

dictionaryはkeyだけになる。

@ No.1731 / 12833

When you give set() a dictionary, it uses only the keys:
