Why does the set function in Python produce different outputs for the same inputs? [duplicate]

Question

This is my code

string='AABCAAADA'
k=3
for i in range(0,len(string),k):
    print(set(string[i:i+k]))

each time I run it produces a different output. how can i fix this?
outputs:

{'B', 'A'}
{'A', 'C'}
{'D', 'A'}

{'B', 'A'}
{'C', 'A'}
{'D', 'A'}

{'A', 'B'}
{'A', 'C'}
{'A', 'D'}

That is outputting the same sets. Set objects are inherently unordered. — juanpa.arrivillaga

Because set() returns set, which by design is unordered collection.
