An example of an AI chatbot conversation about using type hints with Python dataclasses.
How can I use type hints with dataclasses in Python?
You can use type hints in dataclasses by specifying the types of the fields directly in the class definition.
Can you show me an example?
Sure! Here's a simple example:
from dataclasses import dataclass
@dataclass
class Person:
name: str
age: int
In this example, name is a string and age is an integer.
What if I want to have default values?
You can provide default values by assigning them directly in the dataclass definition:
@dataclass
class Person:
name: str
age: int = 30 # Default age is 30
