对未注释的行进行计数，并使用filename写入输出

def count_uncommented_lines(filename, output_filename):
    uncommented_lines = 0

    # 打开输入文件
    with open(filename, 'r') as file:
        lines = file.readlines()

        # 遍历文件中的每一行
        for line in lines:
            # 忽略空行和注释行
            if line.strip() != '' and not line.strip().startswith('#'):
                uncommented_lines += 1

    # 将未注释的行数写入输出文件
    with open(output_filename, 'w') as output_file:
        output_file.write(f"未注释的行数：{uncommented_lines}")

# 调用函数进行测试
count_uncommented_lines('input.txt', 'output.txt')
