我目前正在从 TFL API 中提取天气预报。一旦为“今天的预测”提取了 json,段落中间就会出现随机符号——我认为这可能是从 API 格式化的。
这是提取的内容:
Bank holiday Monday will stay dry with some long sunny spells. Temperatures will remain warm for the time of year.<br/><br/>PM2.5 particle pollution increased rapidly overnight. Increases began across Essex and spread across south London. Initial chemical analysis suggests that this is composed mainly of wood burning particles but also with some additional particle pollution from agriculture and traffic. This would be consistent with an air flow from the continent where large bonfires are part of the Easter tradition. This will combine with our local emissions today and 'high' PM2.5 is possible.<br/><br/>The sunny periods, high temperatures and east winds will bring additional ozone precursors allowing for photo-chemical generation of ozone to take place. Therefore 'moderate' ozone is likely.<br/><br/>Air pollution should remain 'Low' through the forecast period for the following pollutants:<br/><br/>Nitrogen Dioxide<br/>Sulphur Dioxide.
这一段比必要的更详细,前两句话就是我所需要的。我认为.split这是一个好主意,并通过 for 循环运行它,直到它到达 string "<br/><br/>PM2.5"。
但是,我不能确定这是否每天都是相同的字符串,或者简化的预测是否仍然只是前两个句子。
有人对我如何解决这个问题有任何想法吗?
作为参考,这是我目前拥有的代码,它还不是其他任何东西的一部分。
import urllib.parse
import requests
main_api = "https://api.tfl.gov.uk/AirQuality?"
idno = "1"
url = main_api + urllib.parse.urlencode({"$id": idno})
json_data = requests.get(main_api).json()
disclaimer = json_data['disclaimerText']
print("Disclaimer: " + disclaimer)
print()
today_weather = json_data['currentForecast'][0]['forecastText']
print("Today's forecast: " + today_weather.replace("<br/><br/>"," "))
