Does pickled objects work fine between different OS?

[Oltmans]

If I dump a Python dictionary into a file named "data.pkl" using
Pickle module on a Linux operating system, will the data contained in
"data.pkl" load fine in a Windows OS? I mean will I be able to load
the dictionary data contained in "data.pkl" just fine on Windows XP?

I could have tested it but don't have immediate access to a *nix based
system so please enlighten me. All help will be appreciated.

That will work just fine. The only thing that may be a problem is that
if you choose to use the newer pickle format, it won't work with versions
of Python before 2.3.

That depends on the data and the version of Python. Older versions
didn't handle some floating point values (NAN, INF) in a portable
manner, and loading the pickled data would fail when such a value was
encountered.
