探究了餐厅评分的例子，作业本身还算比较简单，基本没有用到什么稀奇的函数。但是学到了代码规范，尤其是 groupby 相关的代码。

给每个测试文件前面添加一行


test_dir = Path("./tests/")
for file in test_dir.rglob ( '*.py' ):
    with open(file, "r+") as t:
        lines = t.readlines()
        if lines[0] != "OK_FORMAT = 1\n":
            lines.insert(0, "OK_FORMAT = 1" + "\n")
            s = ''.join(lines)         
            with open(file, 'w') as f:
                f.write(s)
