Force type conversion in python dataclass __init__ method

Question

I have the following very simple dataclass:

import dataclasses

@dataclasses.dataclass
class Test:
    value: int

I create an instance of t

Answer 1

You could achieve this using the __post_init__ method:

import dataclasses

@dataclasses.dataclass
class Test:
    value : int

    def __post_init__(self):
        self.value = int(self.value)

This method is called following the __init__ method
