No big deal. Using dicts to organize data is quite obvious, and then you
need to operate on these data, so you write functions using these dicts...

Nothing really *requires* classes if you go that way. Now going from
dicts+functions to classes+methods is quite a no-brainer, and can really
ease maintenance. Once you'll be there, you'll probably find yourself
shifting to a more OO style (small decoupled methods, polymorphic
dispatch etc) swithout even noticing. You don't have to learn all the
voodoo stuff about OO to start using OO in Python - but if you already
made the move from strictly procedural (dicts/lists/tuples + functions)
to ADTs (simplest use of classes), you'll be happy to have the whole
power of Python's object model when the need arise.

You're welcome. FWIW, a good exercice would be to take one of your own
programs and try to gradually transform dicts+related funcs to classes.
My 2 cents
