使用这个：anyio （https://github.com/agronholm/anyio)
如果是在fastapi框架里，无需另外安装
否则需要通过pip install anyio来安装
语法上类似标准库pathlib
大致用法如下：
import datetime
from anyio import Path
filepath = Path(__file__)
another = filepath.parent / 'sub_dirpath' / 'filename.ext'
if await another.exists():
content = await another.read_bytes()
elif not await another.parent.exists():
await another.parent.mkdir(parents=True)
else:
await another.write_bytes(b'1')
# glob/stat/remove
async for p in filepath.parent.glob('*'):
if await p.is_file():
stat = await p.stat()
create_time = datetime.fromtimestamp(stat.st_ctime)
update_time = datetime.fromtimestamp(stat.st_mtime)
await p.unlink() # remove file
print(f'{p} created at: {create_time}, modified at: {update_time}, removed at: {datetime.now()}')
