Python - Working around memory leaks

Question

I have a Python program that runs a series of experiments, with no data intended to be stored from one test to another. My code contains a memory leak which I am completely

Answer 1

You can use something like this to help track down memory leaks

>>> from collections import defaultdict
>>> from gc import get_objects
>>> before = defaultdict(int)
>>> after = defaultdict(int)
>>> for i in get_objects():
...     before[type(i)] += 1 
... 

now suppose the tests leaks some memory

>>> leaked_things = [[x] for x in range(10)]
>>> for i in get_objects():
...     after[type(i)] += 1
... 
>>> print [(k, after[k] - before[k]) for k in after if after[k] - before[k]]
[(, 11)]

11 because we have leaked one list containing 10 more lists
