我的jinja for循环格式有问题。它是一个生成名字和姓氏的名字生成器。我在代码中组合了名字和姓氏，但当它输出到HTML文件时，它没有格式化，并且有括号。我真的不确定在哪里修改它，这可能是我错过的一些简单的东西。非常感谢您的帮助。非常感谢。

cs50execute方法返回字典列表。list+list(如total_other = other_name + last_name(返回一个列表，其中包含两个列表中的所有元素。append正在附加一个列表。因此results是一个列表列表，每个列表包含2个字典。解决这个问题的一种方法是将total_{genies}转换为字符串，而不是字典列表，然后附加到results。
每个execute90返回一个列表，该列表恰好包含一个dictionary元素，并且每个dictionary恰好有一个关键字('name'(，因此数据将被寻址为row[0]['name']。然后，为每个(两部分(名称构建一个字符串并附加到结果列表中是基本的。
