使用raw_input()时在目录中查找文件的python选项卡功能

import os

def search_file_in_directory(directory):
    file_name = raw_input("请输入要查找的文件名: ")
    
    file_found = False
    for root, dirs, files in os.walk(directory):
        if file_name in files:
            file_path = os.path.join(root, file_name)
            print("文件已找到: ", file_path)
            file_found = True
            
    if not file_found:
        print("文件未找到.")

# 示例使用，指定要查找的目录
search_file_in_directory("/path/to/directory")
