Class or Dictionary?

I have a series of parameter values which i need to pass throughout my
code (>100), in C I would use a structure for example. However in
python it is not clear to me if it would be better to use a dictionary
or build a class object? Personally I think accessing the values is
neater (visually) with an object rather than a dictionary, e.g.

x = params['price_of_cats'] * params['price_of_elephants']


x = params.price_of_cats * params.price_of_elephants

So currently I am building a series of class objects to hold different
parameters and then passing these through my code, e.g.

class EmptyObject:

self.animal_prices = EmptyObject()
self.price_of_cats = 12 or reading a file and populating the object

I would be keen to hear any reasons why this is a bad approach (if it
is, I haven't managed to work this out)? Or perhaps there is a better
