CPython uses reference counting and a garbage collector that breaks
cycles (see gc.collect). You can use sys.getrefcount() to check the
count (subtract 1 for the call). Also, an extension type may allocate
memory for caches and such (e.g. numpy's fft), and you may not have
direct control over this.

Try a memory profiler:
