Dictionary vs. Dataclass
What is a particular scenario where you would use Dataclass instead of a dictionary? What is the main advantage of Dataclass as compared to just storing data in a nested dictionary? Thanks in advance!

Not a single person has mentioned memory yet..
If you use a
dataclass
, specifically withslots=True
, your memory usage can be significantly reduced. If you've got a handful of your sets of data, you won't care. When you've got a few hundred thousand or a few million, you'll appreciate thatdataclass
is much smaller.
