本文实例讲述了Python实现从百度API获取天气的方法。分享给大家供大家参考。具体实现方法如下：

复制代码 代码如下:__author__ = 'saint'

import os

import urllib.request

import urllib.parse

import json

class weather(object):

# 获取城市代码的uri

code_uri = "http://apistore.baidu.com/microservice/cityinfo"

# 获取天气信息的uri

weather_uri = "http://apistore.baidu.com/microservice/weather"

# 主处理逻辑

def mainHandle(self):

print("输入你要查询的天气：")

city_name = input()

uri = self.code_uri + urllib.parse.quote(city_name)

ret = json.loads(urllib.request.urlopen(uri).read().decode("utf8"))

if ret['errNum'] != 0:

print(ret['retMsg'])

return False

else:

weather_uri = self.weather_uri + ret['retData']['cityCode']

data = json.loads(urllib.request.urlopen(weather_uri).read().decode("utf8"))

if data['errNum'] == 0:

ret_data = data['retData']

output = "城市名:" + city_name + "rn"

output += "更新时间:" + ret_data["date"] + " " + ret_data["time"] + "rn"

output += "天气:" + ret_data["weather"] + " [" + ret_data["WD"] + ret_data["WS"] + "]rn"

output += "当前温度:" + ret_data["temp"] + " (" + ret_data["h_tmp"] + " ---> " + ret_data["l_tmp"] + ")rn"

print(output)

return True

else:

print(data['errMsg'])

return False

if __name__ == "__main__":

weather = weather()

weather.mainHandle()

希望本文所述对大家的Python程序设计有所帮助。
