感谢昨天来自stackoverflow的一些帮助，我的代码取得了进展。但我有一个关于我的页面的问题。这是我的代码

从本质上讲，我的页面可以正常工作，因此您可以从下拉菜单中进行选择（选择以下值之一：例如“高 SAT 分数”和“种族人口统计”会导致我的 python 代码生成一个包含表格或描述的页面）下拉菜单选项）或文本字段（在我的 CSV 文件中搜索状态，并返回包含有关该特定状态的数据的表格行）。使用 cgi.FieldStorage() Python 收集通过 HTML 表单提交的值。但是，如何编写代码，以便仅通过 HTML 表单从文本字段发送值。

即，如果我不想使用下拉菜单，而只想使用文本字段来查找特定的状态，而不是通过下拉菜单提交表单数据，我该怎么做？

我不确定我是否在这里遗漏了一些东西，但是假设“on”是您的文本字段的名称，您可以检查文本字段是否为空，如下所示：

if 'on' in form and form['on']:
    doSomethingWithOn()
else:
    doSomethingWithDrop()
