#- Can you provide more background on the specific problem you need
#- to solve, or are you looking for a very general solution? In
#- other words, do you just need to know how much memory a list, or
#- an integer uses up, or do you think you need a general-purpose
#- function which works with any object of any type.
It's a very general question for a very particular problem, :)
My particular problem is that I want to store in memory a pickled object,
and then want to know if that object changed.
For example (code untested):
""" Class to control if an object changed. """
def __init__(self, object):
objectPickled = cPickle.dumps(object)
def objectChanged(self, newObject):
newObjectPickled = cPickle.dumps(newObject)
if newObjectPickled == self.objectPickled:
object1 = pickle.load(myfile)
control1 = ObjectControl(object1)
#lot of stuff that could change my object
#write to disk only if necessary
Don't know if there's a better solution for this particular problem
(suggestions welcomed), but it still remains a general question: the other
day I wanted to know "how much more expensive in memory is a list than a
tuple for a given content".
Get my idea?
Thanks for all!
