本系统主要包括四个函数:
1、获取天气数据
1、输入要查询天气的城市
2、利用urllib模块向中华万年历天气api接口请求天气数据
3、利用gzip解压获取到的数据,并编码utf-8
4、利用json转化成python识别的数据,返回为天气预报数据复杂形式的字典(字典中的字典)
2、输出当天天气数据
1、格式化输出当天天气,包括:天气状况,此时温度,最高温度、最低温度,风级,风向等。
3,语音播报当天天气
1、创建要输出的语音文本(weather_forecast_txt)
2、利用百度的语音合成模块AipSpeech,合成语音文件
3,利用playsound模块播放语音
4、未来几天温度变化趋势
1、创建未来几天高低温数据的字典
2,利用matplotlib模块,图形化温度变化趋势
