so I did some investigation on the memory use of the script. I found out that when i populated the lists with floats using a for ... in range() loop a lot of overhead memory is used and that this memory is not freed after populating the list and is also not freed after deleting the list.
You didn't say how you "investigated" the memory usage. Note that the Python interpreter does not necessarily free heap memory that it has allocated, even if it is not used anymore. Newly created objects will still end up in that memory area, so nothing is lost.
