+
+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)
+```
+
