The mxTools package adds a new builtin function sizeof, that might do
what you want:
ActivePython 2.1, build 211 (ActiveState)
based on Python 2.1 (#15, Jun 18 2001, 21:42:28) [MSC 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import mx.Tools
>>> dict={"somekey": "somevalue", "anotherkey": 3.1415926535}
>>> sizeof(dict)
44
Neat, eh?
mxTools has other useful stuff, too:
