Data category

Since version 3.7, Python has been able to provide data categories. It has more advantages than regular classes or other alternatives, such as returning multiple values or dictionaries:

Data classes require very little code

Data classes can be compared because _ _ eq__ can implement this function

Data classes require type hints, reducing the possibility of errors

You can easily print data classes for debugging, because _ _ repr__ can achieve this function

This is an example of a working data class:

From dataclasses import dataclass @ dataclass classCard: rank: str suit: str card=Card ("Q", "hearts") print (card= = card) # True print (card.rank) #'Q' print (card) Card (rank='Q', suit='hearts') these are all the contents of this article entitled "what are the advantages of data categories in python".
