首先，我想为令人困惑的标题道歉。
为了提供说明，我有一个列表列表，每个列表都包含唯一值。我想运行 selenium 来点击正确的列表并点击正确的链接。让我们假设我的列表如下所示：
Africa
- South Africa
- Uganda
- etc
Asia
- China
- India
- etc
South America
- Brazil
- Argentina
- etc
我想编写一个用户可以与之交互的交互式代码，以便提供一个可供选择的大陆列表，并根据选择提供有条件的国家/地区列表。让我们假设这是我的代码的第一部分：
geographic_area = input('\n\n\Select a geographic area: South America, Africa, Asia')
driver.find_element_by_css_selector('input[value="{}"]'.format(geographic_area)).click()
在这里，为用户提供了一个可供选择的大陆列表，一旦被选中，就会点击相应的下拉列表。
但是我将如何编写代码的第二部分？我想input()再次使用该功能，但我会有 3 个不同的列表。例如，假设我想选择巴西：为此，我必须首先选择南美洲，然后选择巴西。我该怎么做呢？
以下是有关南美项目的一些信息（很长）：

尝试单击具有精确文本的元素：
continents_countries = {"Asia": ["China", "India", ...],
"Africa": ["South Africa", "Uganda", ...],
"South America": ["Brazil", "Argentina", ...]}
geographic_area = input('\n\n\Select a geographic area: South America, Africa, Asia')
country = input('\n\n\Select a country: %s' % ",".join(continents_countries[geographic_area])
driver.find_element_by_xpath('//label[text()="{}"]'.format(geographic_area)).click()
driver.find_element_by_xpath('//label[text()="{}"]'.format(country)).click()
