实践项目四:桌面版python 查询天气(3)

2017-07-10 16:15 441 查看

完善

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

import requests
import json
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:
