在目录中搜索特定文件扩展名并执行求和运算以将其内容相加的后续操作

import os

def search_and_sum_files(directory, extension):
    total_sum = 0

    for root, dirs, files in os.walk(directory):
        for file in files:
            file_path = os.path.join(root, file)
            file_extension = os.path.splitext(file_path)[1]

            if file_extension == extension:
                with open(file_path, 'r') as f:
                    content = f.read()
                    # 根据文件内容的格式进行求和运算
                    # 这里假设文件内容是一行一个数字
                    numbers = content.split('\n')
                    numbers = [int(num) for num in numbers if num.isdigit()]
                    file_sum = sum(numbers)
                    total_sum += file_sum

    return total_sum

# 示例用法
directory = '/path/to/directory'  # 替换为目标目录的路径
extension = '.txt'  # 替换为目标文件的扩展名
result = search_and_sum_files(directory, extension)
print("总和：", result)
