参考廖雪峰的Python教程，实现Linux Python3获取雅虎天气

#!/usr/bin/env python3# coding: utf-8import osfrom datetime import datetimefrom urllib import request from xml.parsers.expat import ParserCreate file_name = "weather.txt"for root, dirs, files in os.walk("."): if file_name in files: os.remove(os.path.join(root, file_name))def yahoo_weather(data): flag = False weather = {"city": "", "pubdate": "", "forecast": []} def start_element(name, attrs): if name == "yweather:location": weather["city"] = weather["city"] + attrs["city"] weather["city"] = weather["city"] + " " + attrs["country"] if name == "yweather:forecast": forecast = {} forecast["date"] = attrs["date"] forecast["day"] = attrs["day"] forecast["high"] = attrs["high"] forecast["low"] = attrs["low"] forecast["text"] = attrs["text"] weather["forecast"].append(forecast) if name == "pubDate": nonlocal flag flag = True def char_data(text): nonlocal flag if flag: weather["pubdate"] = text flag = False parser = ParserCreate() parser.StartElementHandler = start_element parser.CharacterDataHandler = char_data parser.Parse(data) return weatherdef print_weather(weather): with open(file_name, "a") as f: s = "City: %s\nPub date: %s" %(weather["city"], weather["pubdate"]) print("%s" %(weather["city"])) f.write(s + "\n") for forecast in weather["forecast"]: date = datetime.strptime(forecast["date"], "%d %b %Y").strftime("%Y-%m-%d") s = "Date: %s High: %s Low: %s Weather: %s" %(date, forecast["high"], forecast["low"], forecast["text"]) f.write(s + "\n") f.write("\n")citys = ["2151330", "2151849", "44418", "615702", "2514815"]for city in citys: url = "https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%20%3D%20" url = url + city url = url + "&format=xml" with request.urlopen(url, timeout=4) as f: weather = yahoo_weather(f.read()) print_weather(weather)print("weather conditions has written to %s" %(file_name))
