复制目录结构+文件，但排除文件名中包含备份字的文件

import os
import shutil

def copy_directory(source_dir, target_dir):
    for root, dirs, files in os.walk(source_dir):
        for file in files:
            if '备份' not in file:
                source_file = os.path.join(root, file)
                target_file = os.path.join(target_dir, os.path.relpath(source_file, source_dir))
                target_dir = os.path.dirname(target_file)
                os.makedirs(target_dir, exist_ok=True)
                shutil.copy2(source_file, target_file)

source_dir = '/path/to/source/directory'
target_dir = '/path/to/target/directory'

copy_directory(source_dir, target_dir)
