I'm currently trying my hands on the new dataclass constructions introduced in Python 3.7. I am currently stuck on trying to do some inheritance of a parent class. It looks like the order of the arguments are botched by my current approach such that the bool parameter in the child class is passed before the other parameters. This is causing a type error.
from dataclasses import dataclass
@dataclass
class Parent:
name: str
age: int
ugly: bool = False
def print_name(self):
print(self.name)
def print_age(self):
print(self.age)
def print_id(self):
print(f'The Name is {self.name} and {self.name} is {self.age} year old')
@dataclass
class Child(Parent):
school: str
ugly: bool = True
jack = Parent('jack snr', 32, ugly=True)
jack_son = Child('jack jnr', 12, school = 'havard', ugly=True)
print(jack.print_id())
print(jack_son.print_id())
When I run this code I get this TypeError:
TypeError: non-default argument 'school' follows default argument
How do I fix this?
