我正在使用来自RapidApi的REST，我成功地打印了整个响应，但是我只需要一些特定的参数。比如，只打印12月和到达时间。当使用params:{}时，没有帮助，因为这会打印带有指定参数的每个参数。我需要逆，以打印一个特定的参数与更多的参数。

代码语言：javascript
运行
复制
import requests
url = "https://timetable-lookup.p.rapidapi.com/TimeTable/LHR/BCN/20221119/"

headers = {
    "X-RapidAPI-Key": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    "X-RapidAPI-Host": "timetable-lookup.p.rapidapi.com"
}

response = requests.request("GET",url,headers=headers, params=querystring)
print(response.text)

API响应如下：

尝试使用xml.etree.ElementTree包解析输出。从那里开始，您应该能够在xml树中搜索相关数据并显示它。

下面是一个让你开始学习的片段：

代码语言：javascript
运行
复制
# create element tree object
tree = ET.parse(xmlfile)
  
# get root element
root = tree.getroot()

从那里，您可以使用树结构从根搜索。文档在这里，https://docs.python.org/3/library/xml.etree.elementtree.html
