编写查找文件夹下一堆文件中那个文件藏有flag的Python脚本

import os

def search_flag_files(folder_path, flag):
    flag_files = []
    for root, dirs, files in os.walk(folder_path):
        for file in files:
            file_path = os.path.join(root, file)
            try:
                with open(file_path, 'r', encoding='utf-8') as f:
                    content = f.read()
                    if flag in content:
                        flag_files.append(file_path)
            except Exception as e:
                print(f"Error reading file {file_path}: {e}")
    return flag_files

if __name__ == "__main__":
    folder_path = "/root/桌面/flag"      #藏有flag的文件夹
    flag = "{"      #查找文件夹下的文件中含有“{”的文件
    flag_files = search_flag_files(folder_path, flag)
    if flag_files:
        print("Files containing the flag:")
        for file in flag_files:
            print(file)
    else:
        print("No files containing the flag were found.")
