It most decisively does *not* format the results of the system call
"for display". Instead, it converts the C data type holding the
stat result into a Python data type. That data type historically
was a tuple, but now is struct-like type with the same fields as
the C data type.
It's the same as saying "+ does not do addition. It does a lot
of other stuff, including the formatting of the result of the
operation for display".

This is probably a matter of opinion. I think it is important
to understand that Python does *not* do any significant code
to os.stat and os.lstat; entirely unlike libraries in other
languages that attempt to also change the programming API in
the process of wrapping the system API.
