python在某个目录下的查找指定文件夹

import shutil
from pathlib import Path

file_filter = ["200818", "00200258", "200555", "200358"]
source_path = "/Users/shaomengchen/source" #源路径
target_path = "/Users/shaomengchen/backup" #目标路径

source = Path(source_path)
target = Path(target_path)

# 合并正则：002开头8位 或 2开头6位
pattern = r'^(002\d{5}|2\d{5})$'

for folder in source.rglob('*'):
    if folder.is_dir() and (folder.name in file_filter or f'00{folder.name}' in file_filter):
        print(f'目录路径：{folder.absolute()}，目录文件数:{sum(1 for item in folder.iterdir() if item.is_file())}')
        #print(f'{folder.absolute()}/{folder.name}, {target.absolute()}/{folder.name}')
        shutil.copytree(f'{folder.absolute()}',f'{target.absolute()}/{folder.name}', dirs_exist_ok=True)
