Dictionary of "structs" with functions as components?

[Eric Sandeen]

First a disclaimer - I'm pretty new to Python, and OOP is not really my
bag, so forgive me if this is a silly question...

I'm trying to create a data structure which holds information about
several different filesystems - for example: ext2, reiserfs, and xfs. I'd
like this to be easily extensible to add other filesystems, as well. The
type of information I'm including is name, magic number, position of magic
number in superblock, etc.  So far, I'm doing something like this (these
values aren't right, just an example) :

FSystems['ext2'].PrettyName = "ext2 filesystem" 
FSystems['ext2'].MagicNo = 0xce32
FSystems['ext2'].MagicNoPos = 1080

FSystems['xfs'].PrettyName = "XFS filesystem" 
FSystems['xfs'].MagicNo = "XFSB"
FSystems['xfs'].MagicNoPos = 0

This way I can iterate over FSystems.keys() to do things like check for a
filesystem, create menus, etc.  These activities are basically the same
regardless of the filesystem, so they're easy to handle in a single
function.

The problem comes when I'd like to define a unique function for each
filesystem to actually create the filesystem, since this will vary quite a
bit from fs to fs.  I'd like to access it via something like

FSystems[<fstype>].unique_fs_function()

In C, I'd have a pointer to the function I want.  Is something like this
possible in Python?

Thanks,
