Thee is no definitive answer but here are some
guidelines:
1) Many instances -> class
2) Many methods sharing the same data -> class
3) An algorithm that has no side effects -> a function
Very often we start with a function then realize it
would be better in a class.
In general classes need more code but provide more
maintainable and reusable solutions. so on a bigger
project classes are likely to be a better option.
Pythons module/package mechanism is quite powerful
so often we don't need classes where other
languages would use them.
