```bash mkdir pytowebp && cd $_ python -m venv venv –upgrade-deps . venv/env/activate (venv) pip install Pillow (venv) emacs main.py ```

main.py:

```py from pathlib import Path from PIL import Image

def convert<sub>towebp</sub>(source): """Convert image to webp.

Args: source (pathlib.Path): Path to source image

Returns: pathlib.Path: path to new image """ destination = source.with<sub>suffix</sub>(".webp")

image = Image.open(source) # Open image image.save(destination, format="webp") # Convert image to webp

return destination

def main(): all<sub>filespath</sub> = Path(".").glob(r"*/") for single<sub>file</sub> in all<sub>filespath</sub>: if single<sub>file</sub>.suffix in {".png", ".jpg", ".jpeg"}: # PurePath.suffix 查询文件扩展名 webp<sub>path</sub> = convert<sub>towebp</sub>(single<sub>file</sub>) print(webp<sub>path</sub>)

main() ```

最难的部分是同时找到包含 `{".png", ".jpg", ".jpeg"}` 三种后缀的文件。
