In documentation it is written that " Sets are unordered collection", but actually it is storing the elements in sorted order.

[stevendaprano]

"Unordered" means that the language doesn't promise any specific order, it doesn't mean that there is no order at all.

Try strings:

py> set("abcdef")
{'b', 'f', 'c', 'e', 'd', 'a'}

or different ints:

py> set([1, 0, -2])
{0, 1, -2}

[stevendaprano]

Here's another example:

py> set([1, 2**63, 4, -5, 6, 5])
{1, 9223372036854775808, 4, 6, 5, -5}

By the way, in the future, please don't post screen shots of text, copy the code and output and paste it as text into your bug report. Screenshots make it hard for us to reproduce the bug, we have to re-type your code. And it makes it difficult for blind and visually impaired developers, who may be reading this with a screen-reader.
