Re: Can I export my datas in pickle format safely ?

DurumDara enlightened us with:
I want to create a database from datas.

Just nitpicking: 'data' is already plural, a single is called 'datum'.

I thinking about that I can use the pickle to serialize/load my
datas from the file.

Sure you can. Be very, very careful though, since unpickling data can
result in that data taking over your Python.

And when I changed my python version from ??? to 2.3(?), and I get
some error messages...

Which is exactly as documented in the pickle module.

So: I want to store datas in the simply as possible, but I don't
want to get error messages in the future, when I upgrade a new
python version.

Without knowing more about your data, I can't help you out. You could
try an SQLite database.

I see that the Gnosis project have pickle tools that can dump
objects to XML. XML is compatible in any future versions, I can
read it, etc.

Don't be too sure that it's compatible for the indefinite future. XML
is just as future-proof as any other format.
