As others have already pointed out, a process which doesn't exist can't
use memory (on Linux or any other sane OS). So either python is still
running or something else is using the memory.
To find out what is using the memory, run the command
top
in a terminal. Then press Shift-M to sort processes by memory
consumption. The offenders should now be at the top.
