List memory usage

Question

I am trying to improve the memory usage of my script in python, therefore I need to know what\'s RAM usage of my list. I measure the memory usage with

print          


        

Answer 1

sys.getsizeof only take account of the list itself, not items it contains.

According to sys.getsizeof documentation:

... Only the memory consumption directly attributed to the object is accounted for, not the memory consumption of objects it refers to. ...

Use Pympler:

>>> import sys
>>> from pympler.asizeof import asizeof
>>>
>>> obj = [1, 2, (3, 4), 'text']
>>> sys.getsizeof(obj)
48
>>> asizeof(obj)
176
