pysize
Use to quickly measure the size of your python objects. Supports:
- Measuring the size of self-referential objects
- No double-counting for repeated objects in a collection
- Python v2/v3
Examples:
>>> class Test(object):
>>> pass
>>> from pysize import get_size
>>> z = Test()
>>> get_size(z)
344
>>> y = [z] * 10000
>>> get_size(y)
80416
>>> z.l = ["test"*100]
>>> get_size(z)
899
>>> get_size(y)
80971
To measure the size of properties
, call pysize.get_size
on the full list
of the object's members minus overhead and unwanted memberes:
import pysize
class Ping(object):
@property
def ping(self):
return 'pong'
class B(Ping):
@property
def marko(self):
return 'polo'
obj = B()
to_measure = [getattr(obj, prop) for prop in dir(obj)\
if prop not in dir(Ping)] # Exclude inherited attrs
empty_list_size = pysize.get_size([])
pysize.get_size(to_measure) - empty_list_size - 8 * len(to_measure)
