1.实现了直接输入城市名字查询
2.信息更多样化
3.前面是获取网页信息后，通过正则表达式匹配，这次使用eval()转换为字典，提取字典中的元素。
4.这次的API接口：点击打开链接，另外附上一个Python天气查询的不错的教程：点击打开链接
importrequests
importjson
url ='http://wthrcdn.etouch.cn/weather_mini?citykey=%s'%'101010100'
response = requests.request("GET", url)
a = eval(response.content)
print(a)
print('城市：'+a.get('data').get('city')+'\n''温度：'+a.get('data').get('wendu')+'℃\n''感冒：'+a.get('data').get('ganmao'))
获取的信息：
{'status':1000,'desc':'OK','data': {'aqi':'75','city':'北京','forecast': [{'low':'低温 23℃','fengli':'微风级','date':'10日星期一','type':'晴','high':'高温 36℃','fengxiang':'南风'}, {'low':'低温 27℃','fengli':'微风级','date':'11日星期二','type':'多云','high':'高温 36℃','fengxiang':'南风'}, {'low':'低温 27℃','fengli':'微风级','date':'12日星期三','type':'多云','high':'高温 35℃','fengxiang':'南风'}, {'low':'低温 27℃','fengli':'微风级','date':'13日星期四','type':'多云','high':'高温 36℃','fengxiang':'南风'}, {'low':'低温 26℃','fengli':'微风级','date':'14日星期五','type':'雷阵雨','high':'高温 35℃','fengxiang':'南风'}],'yesterday': {'fx':'东北风','low':'低温 24℃','type':'多云','date':'9日星期日','high':'高温 35℃','fl':'微风'},'ganmao':'各项气象条件适宜，发生感冒机率较低。但请避免长期处于空调房间中，以防感冒。','wendu':'36'}}
城市：北京
温度：36℃
感冒：各项气象条件适宜，发生感冒机率较低。但请避免长期处于空调房间中，以防感冒。
5.本来想添加背景图片呢，百度了一天，也没弄上，烦死啦。。。。。如果有哪位大神会的话，带带我
6.完成的界面：
