You can do

when you don't know whether x is a float, int, or str. Not terribly useful,

Hi,
I usually works with packages like pyserial, numpy, mathplotlib,pyUSB, etc..
When is planned that these packages are supported in Python 3.0?
Seen this i would say that is not recommendable to use Python 3.0 at the
moment? most of 2.6 packages are not available, not working in python 3.0.

By the way, I hate wildcard imports. In the ctypes docs, they recommend you
do this
from ctypes import *
but I prefer this:
import ctypes as ct
which explains the "ct.
how about this :
- dump those data with sort enabled
- use diff to those two dumps , eg: diff dump_a dump_b
if you don't know what diff is , try : man diff

not really a conspiracy but it is not that trivial
In wrapping c++ you might find useful the commands nm with c++filt
although they work under linux there is the same pair for every platform
(under windows I remember there is objdump): they should only you need to wrap
a c++ library.
