What does gc.get_objects() return?

[Jurko Gospodnetiæ]

Hi all.

I was wondering if someone could explain gc.get_objects() in a bit
more detail to me.

Does it return a list of 'all objects known to Python'? Only some of
them? Which does it return? Which it does not?

For example (done using CPython 3.4 interactive interpreter) here it
does not contain an object I know exists:

False

but here it does:

True

It also does not seem to contain string objects. At first I thought
that perhaps interned strings were not placed under GC control, so I
tested this:

False

Which shows that non-interned scripts such as these are not getting
listed in gc.get_objects() either. :-s

Many thanks.

Best regards,
