递归检查dir是否包含文件并提前退出

import os

def recursive_search_dir(directory, target_file):
    # 检查当前目录是否包含目标文件
    for file in os.listdir(directory):
        if file == target_file:
            return True

    # 递归搜索子目录
    for sub_dir in os.listdir(directory):
        sub_dir_path = os.path.join(directory, sub_dir)
        if os.path.isdir(sub_dir_path):
            if recursive_search_dir(sub_dir_path, target_file):
                return True

    return False

# 调用示例
directory = '/path/to/directory'  # 替换为实际的目录路径
target_file = 'target_file.txt'  # 替换为实际的目标文件名
result = recursive_search_dir(directory, target_file)
if result:
    print("目录中包含目标文件")
else:
    print("目录中不包含目标文件")
