Even a function is commonly defined without giving it a name.

That assumes that the object has exactly one

The thing about functions or classes is that you can't (at the literal
source level) define them *without* giving them a name:

I recommend tracemalloc.
Start with PYTHONTRACEMALLOC=3, and increase depth only when stack trace is
too short.

This is application-specific, but sometimes it helps to look at the
objects' types, or even their values.
The types are dict and list, so they are not very use

I have a script that consumes more and more memory as it runs. It has
no globals and the large data structures go out of scope often so
should be garbage collected. I've looked at the most likely suspects
with sys.getsizeof and they are not growing in size. I did this:
sum([sys.getsizeof(o) for o
24 matches
