# Python Style

- use python 3.12 or above
- all function must be type hinted
- use latest type hints syntax, eg.
  - `list[int]` instead of `List[int]`
  - `dict[str, int]` instead of `Dict[str, int]`
  - `tuple[int, ...]` instead of `Tuple[int, ...]`
  - `A | B` instead of `Union[A, B]`
  - use `typing.Self` instead of forward reference string "ClassName"

# Docstrings Style

- use Google style docstrings
- don't write type hints in docstrings
- refer to the following example:

```python
def sample_function(param1: int, param2: str) -> bool:
"""
Example function with PEP 484 type annotations.

Args:
    param1: The first parameter.
    param2: The second parameter.

Returns:
    The return value. True for success, False otherwise.
"""
```

# CSS Style

- use nested selectors to style components
- try to use variables for colors, sizes, etc.
