遍历目录中的所有.txt文件，找到一个特定值，然后计算.txt文件中所有值的总和

import os

    total_sum = 0
    found_files = []

    for root, dirs, files in os.walk(directory):
        for file in files:
            if file.endswith(".txt"):

                with open(file_path, 'r') as f:
                    for line in f:

                            found_files.append(file_path)
                            values = line.split()

                                except ValueError:
                                    pass

    return found_files, total_sum

directory = "/path/to/directory"  # 替换为实际目录路径
target_value = "特定值"  # 替换为实际要搜索的特定值
