Why does Python Set automatically re-sorting my inputted set?

Question

below is my code, and when I print or use the Python set, it automatically re-sort my item, why does this happen?

a = {9,40,49}
print(a)

{40, 9, 49}

Below is notebook printed image.

Oh! Been trying to figure out why for such a long time, thank you. — Wing Shum, May 17 '20 at 14:40
How much time exactly? A simple "python set order" google would reveal the answer — Tomerikoo, May 17 '20 at 14:55

Sets are an unordered data structure. However, depending on your use case, it might be appropriate to use a different data type such as list.
