Python DRY

python
Avoid duplicating code in Python. Extract repeated logic into reusable functions, classes, or constants. You may have to search the codebase to see if the function or class is already defined.
Bad:
```python
# Duplicated class definitions
class User:
    def __init__(self, id: str, name: str):
        self.id = id
        self.name = name
