Python 3.7 and above have a feature called dataclasses. This allows us to reduce boilerplate code by removing the need to create a whole constructor and providing a sensible `__repr__` function.
```python
from dataclasses import dataclass
@dataclass
class Person:
name: str
age: int = 0
```
Usage:
p = Person("Bob", 30)
print(p)
Person(name='Bob', age=20)
To make an attribute have a default value, add it after the type declaration like I have with `age`.
