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
|
||
|
|
```
|
||
|
|
|
||
|
|
Usage:
|
||
|
|
|
||
|
|
```python
|
||
|
|
p = Person("Bob", 30)
|
||
|
|
print(p)
|
||
|
|
```
|
||
|
|
|
||
|
|
```
|
||
|
|
Person(name='Bob', age=20)
|
||
|
|
```
|
