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.
