将两个目录的内容交织到一个新目录中

import os
import shutil

def interweave_directories(source_dir1, source_dir2, target_dir):
    # 创建目标目录
    os.makedirs(target_dir, exist_ok=True)

    # 遍历第一个目录，复制文件和子目录到目标目录
    for root, dirs, files in os.walk(source_dir1):
        for file in files:
            source_path = os.path.join(root, file)
            target_path = os.path.join(target_dir, file)
            shutil.copy2(source_path, target_path)

    # 遍历第二个目录，复制文件和子目录到目标目录
    for root, dirs, files in os.walk(source_dir2):
        for file in files:
            source_path = os.path.join(root, file)
            target_path = os.path.join(target_dir, file)
            if os.path.exists(target_path):
                # 如果目标目录已存在同名文件，可以选择覆盖或重命名
                # 这里选择重命名，添加一个后缀
                target_path = os.path.join(target_dir, file + "_2")
            shutil.copy2(source_path, target_path)

# 示例用法
source_dir1 = "/path/to/source_dir1"
source_dir2 = "/path/to/source_dir2"
target_dir = "/path/to/target_dir"

interweave_directories(source_dir1, source_dir2, target_dir)
