自学教程：Python脚本制作天气查询实例代码

# cityCode 替换为具体某一个城市的对应编号# 1、发送请求，获取数据url = f'http://wthrcdn.etouch.cn/weather_mini?citykey={cityCode}'res = requests.get(url)res.encoding = 'utf-8'res_json = res.json() # 2、数据格式化data = res_json['data']city = f"城市：{data['city']}/n"  # 字符串格式化的一种方式 f"{}" 通过字典传递值 today = data['forecast'][0]date = f"日期：{today['date']}/n"  # /n 换行now = f"实时温度：{data['wendu']}度/n"temperature = f"温度：{today['high']} {today['low']}/n"fengxiang = f"风向：{today['fengxiang']}/n"type = f"天气：{today['type']}/n"tips = f"贴士：{data['ganmao']}/n" result = city + date + now + temperature + fengxiang + type + tips print(result)

# 1、清空按钮与对应函数连接clearBtn.clicked.connect(widget.clearResult) # 2、查询按钮与对应函数连接queryBtn.clicked.connect(widget.queryWeather)
