Another option would be for you to use XML and base it off of a schema.
There's a really nifty tool called generate DS (just google it) that will
turn any valid schema into a python module.
I pasted an example schema that you might use here:
http://pastebin.com/AVgVGpgu
Once you install generateds, just cd to where it is installed and type:
python generateds.py -o pn.py PhoneNumber.xsd
This assumes you named the above schema as PhoneNumber.xsd
That will create a file called pn.py. For some reason it generated a bad
line on line 452, which I just commented out.
I then made a script in just a few lines to make a phonebook:
http://pastebin.com/h4JB0MkZ
This outputs XML that looks like this:
<PhoneBook>
> <Listing>
> <PersonsName>aaa</PersonsName>
> <Number Type="Mobile">
> <Number>1231231234</Number>
> </Number>
> </Listing>
> <Listing>
> <PersonsName>bbb</PersonsName>
> <Number Type="Work">
> <Number>1231231234</Number>
> </Number>
> <Number Type="Home">
> <Number>6789231234</Number>
> </Number>
> </Listing>
> <Listing>
> <PersonsName>ccc</PersonsName>
> <Number Type="Fax">
> <Number>1231231234</Number>
> </Number>
> </Listing>
> <Listing>
> <PersonsName>ddd</PersonsName>
> <Number Type="Home">
> <Number>1231231234</Number>
> </Number>
> </Listing>
> </PhoneBook>
The advantage is, you can immediately grab the generated xml and create
python instances using the build() method for further editing. You would of
course need to create a schema that fits your needs. Mine was just a quick
and dirty example of what you could do.
