python - Usage of multiple dicts versus a single dict of class instances -

i'm looking @ code loads data in following way:

idtofoo, idtobar, idtobaz = loadflibbets() 

each of these dict between id , corresponding data value.

this used in way similar to:

for id in idtofoo:     foo = idtofoo[id]     bar = idtobar[id]     baz = idtobaz[id]     # process flibbet 

my oo pattern of thinking tells me code easier understand if define class held foo, bar , baz properties fields, , changed resembling:

flibbets = loadflibbets()  flibbet in flibbets:     # process flibbet using flibbet.foo, flibbet.bar , flibbet.baz 

which more pythonic approach? i'm relatively new python , i've inherited code find quite hard reason about, may need think differently. more python experience comment?
