在多个文件夹中运行，找到特定文件，将内容复制到python中的另一个文件中

import os

def find_and_copy_files(source_folder, target_file):
    for root, dirs, files in os.walk(source_folder):
        for file in files:
            if file.endswith('.txt'):  # 判断文件名以.txt结尾，可以根据实际需求修改条件
                file_path = os.path.join(root, file)
                with open(file_path, 'r') as f:
                    content = f.read()
                with open(target_file, 'a') as f:
                    f.write(content)

# 示例调用
source_folder = '/path/to/source/folder'  # 指定源文件夹路径
target_file = '/path/to/target/file.txt'  # 指定目标文件路径
find_and_copy_files(source_folder, target_file)
